https://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.13.5

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel packages installed that are affected by multiple vulnerabilities:

  - The iscsi_if_rx function in drivers/scsi/scsi_transport_iscsi.c in the Linux kernel through 4.13.2 allows     local users to cause a denial of service (panic) by leveraging incorrect length validation.
    (CVE-2017-14489)

  - In the Linux kernel before 4.13.5, a local user could create keyrings for other users via keyctl commands,     setting unwanted defaults or causing a denial of service. (CVE-2017-18270)

  - In the Linux kernel before 5.2.10, there is a use-after-free bug that can be caused by a malicious USB     device in the drivers/hid/usbhid/hiddev.c driver, aka CID-9c09b214f30e. (CVE-2019-19527)

  - A flaw was found in the Linux Kernel in versions after 4.5-rc1 in the way mremap handled DAX Huge Pages.
    This flaw allows a local attacker with access to a DAX enabled storage to escalate their privileges on the     system. (CVE-2020-10757)

  - An issue was found in Linux kernel before 5.5.4. The mwifiex_cmd_append_vsie_tlv() function in     drivers/net/wireless/marvell/mwifiex/scan.c allows local users to gain privileges or cause a denial of     service because of an incorrect memcpy and buffer overflow, aka CID-b70261a288ea. (CVE-2020-12653)

  - An issue was found in Linux kernel before 5.5.4. mwifiex_ret_wmm_get_status() in     drivers/net/wireless/marvell/mwifiex/wmm.c allows a remote AP to trigger a heap-based buffer overflow     because of an incorrect memcpy, aka CID-3a9b153c5591. (CVE-2020-12654)

  - The VFIO PCI driver in the Linux kernel through 5.6.13 mishandles attempts to access disabled memory     space. (CVE-2020-12888)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - drivers/gpu/msm/kgsl.c in the MSM graphics driver (aka     GPU driver) for the Linux kernel 3.x, as used in     Qualcomm Innovation Center (QuIC) Android contributions     for MSM devices and other products, mishandles the     KGSL_MEMFLAGS_GPUREADONLY flag, which allows attackers     to gain privileges by leveraging accidental read-write     mappings, aka Qualcomm internal bug     CR988993.(CVE-2016-2067i1/4%0

  - Integer overflow in the mem_check_range function in     drivers/infiniband/sw/rxe/rxe_mr.c in the Linux kernel     before 4.9.10 allows local users to cause a denial of     service (memory corruption), obtain sensitive     information from kernel memory, or possibly have     unspecified other impact via a write or read request     involving the 'RDMA protocol over infiniband' (aka Soft     RoCE) technology.(CVE-2016-8636i1/4%0

  - Heap-based buffer overflow in the     logi_dj_ll_raw_request function in     drivers/hid/hid-logitech-dj.c in the Linux kernel     before 3.16.2 allows physically proximate attackers to     cause a denial of service (system crash) or possibly     execute arbitrary code via a crafted device that     specifies a large report size for an LED     report.(CVE-2014-3183i1/4%0

  - The futex_requeue function in kernel/futex.c in the     Linux kernel, before 4.14.15, might allow attackers to     cause a denial of service (integer overflow) or     possibly have unspecified other impacts by triggering a     negative wake or requeue value. Due to the nature of     the flaw, privilege escalation cannot be fully ruled     out, although we believe it is     unlikely.(CVE-2018-6927i1/4%0

  - The hub_activate function in drivers/usb/core/hub.c in     the Linux kernel before 4.3.5 does not properly     maintain a hub-interface data structure, which allows     physically proximate attackers to cause a denial of     service (invalid memory access and system crash) or     possibly have unspecified other impact by unplugging a     USB hub device.(CVE-2015-8816i1/4%0

  - It was found that the blk_rq_map_user_iov() function in     the Linux kernel's block device implementation did not     properly restrict the type of iterator, which could     allow a local attacker to read or write to arbitrary     kernel memory locations or cause a denial of service     (use-after-free) by leveraging write access to a     /dev/sg device.(CVE-2016-9576i1/4%0

  - A security flaw was found in the Linux kernel's     networking subsystem that destroying the network     interface with huge number of ipv4 addresses assigned     keeps 'rtnl_lock' spinlock for a very long time (up to     hour). This blocks many network-related operations,     including creation of new incoming ssh connections.The     problem is especially important for containers, as the     container owner has enough permissions to trigger this     and block a network access on a whole host, outside the     container.(CVE-2016-3156i1/4%0

  - The edge_bulk_in_callback function in     drivers/usb/serial/io_ti.c in the Linux kernel allows     local users to obtain sensitive information (in the     dmesg ringbuffer and syslog) from uninitialized kernel     memory by using a crafted USB device (posing as an     io_ti USB serial device) to trigger an integer     underflow.(CVE-2017-8924i1/4%0

  - The IPv4 implementation in the Linux kernel before     3.18.8 does not properly consider the length of the     Read-Copy Update (RCU) grace period for redirecting     lookups in the absence of caching, which allows remote     attackers to cause a denial of service (memory     consumption or system crash) via a flood of     packets.(CVE-2015-1465i1/4%0

  - A symlink size validation was missing in Linux kernels     built with UDF file system (CONFIG_UDF_FS) support,     allowing the corruption of kernel memory. An attacker     able to mount a corrupted/malicious UDF file system     image could cause the kernel to crash.(CVE-2014-9728i1/4%0

  - net/ipv6/ip6_output.c in the Linux kernel through     3.11.4 does not properly determine the need for UDP     Fragmentation Offload (UFO) processing of small packets     after the UFO queueing of a large packet, which allows     remote attackers to cause a denial of service (memory     corruption and system crash) or possibly have     unspecified other impact via network traffic that     triggers a large response packet.(CVE-2013-4387i1/4%0

  - It was found that nfsd is missing permissions check     when setting ACL on files, this may allow a local users     to gain access to any file by setting a crafted     ACL.(CVE-2016-1237i1/4%0

  - In the Linux kernel before 4.13.5, a local user could     create keyrings for other users via keyctl commands,     setting unwanted defaults or causing a denial of     service.(CVE-2017-18270i1/4%0

  - An issue was discovered in the Linux kernel where an     integer overflow in kernel/time/posix-timers.c in the     POSIX timer code is caused by the way the overrun     accounting works. Depending on interval and expiry time     values, the overrun can be larger than INT_MAX, but the     accounting is int based. This basically makes the     accounting values, which are visible to user space via     timer_getoverrun(2) and siginfo::si_overrun,     random.(CVE-2018-12896i1/4%0

  - Since Linux kernel version 3.2, the mremap() syscall     performs TLB flushes after dropping pagetable locks. If     a syscall such as ftruncate() removes entries from the     pagetables of a task that is in the middle of mremap(),     a stale TLB entry can remain for a short time that     permits access to a physical page after it has been     released back to the page allocator and reused. This is     fixed in the following kernel versions: 4.9.135,     4.14.78, 4.18.16, 4.19.(CVE-2018-18281i1/4%0

  - The netfilter subsystem in the Linux kernel through     4.15.7 mishandles the case of a rule blob that contains     a jump but lacks a user-defined chain, which allows     local users to cause a denial of service (NULL pointer     dereference) by leveraging the CAP_NET_RAW or     CAP_NET_ADMIN capability, related to arpt_do_table in     net/ipv4/netfilter/arp_tables.c, ipt_do_table in     net/ipv4/netfilter/ip_tables.c, and ip6t_do_table in     net/ipv6/netfilter/ip6_tables.c.(CVE-2018-1065i1/4%0

  - The use of a kzalloc with an integer multiplication     allowed an integer overflow condition to be reached in     vfio_pci_intrs.c. This combined with CVE-2016-9083 may     allow an attacker to craft an attack and use     unallocated memory, potentially crashing the     machine.(CVE-2016-9084i1/4%0

  - The acm_probe function in drivers/usb/class/cdc-acm.c     in the Linux kernel before 4.5.1 allows physically     proximate attackers to cause a denial of service (NULL     pointer dereference and system crash) via a USB device     without both a control and a data endpoint     descriptor.(CVE-2016-3138i1/4%0

  - It was discovered that root can gain direct access to     an internal keyring, such as '.dns_resolver' in RHEL-7     or '.builtin_trusted_keys' upstream, by joining it as     its session keyring. This allows root to bypass module     signature verification by adding a new public key of     its own devising to the keyring.(CVE-2016-9604i1/4%0

  - An information leak flaw was found in the Linux     kernel's IEEE 802.11 wireless networking     implementation. When software encryption was used, a     remote attacker could use this flaw to leak up to 8     bytes of plaintext.(CVE-2014-8709i1/4%0

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - The perf_cpu_time_max_percent_handler function in     kernel/events/core.c in the Linux kernel before 4.11     allows local users to cause a denial of service     (integer overflow) or possibly have unspecified other     impact via a large value, as demonstrated by an     incorrect sample-rate calculation.(CVE-2017-18255)

  - In the Linux kernel before 4.13.5, a local user could     create keyrings for other users via keyctl commands,     setting unwanted defaults or causing a denial of     service.(CVE-2017-18270)

  - The timer_create syscall implementation in     kernel/time/posix-timers.c in the Linux kernel doesn't     properly validate the sigevent-i1/4zsigev_notify field,     which leads to out-of-bounds access in the show_timer     function.(CVE-2017-18344)

  - arch/x86/kvm/emulate.c in the Linux kernel through     4.9.3 allows local users to obtain sensitive     information from kernel memory or cause a denial of     service (use-after-free) via a crafted application that     leverages instruction emulation for fxrstor, fxsave,     sgdt, and sidt.(CVE-2017-2584)

  - Linux kernel built with the KVM visualization support     (CONFIG_KVM), with nested visualization(nVMX) feature     enabled(nested=1), is vulnerable to host memory leakage     issue. It could occur while emulating VMXON instruction     in 'handle_vmon'. An L1 guest user could use this flaw     to leak host memory potentially resulting in     DoS.(CVE-2017-2596)

  - A race condition flaw was found in the N_HLDC Linux     kernel driver when accessing n_hdlc.tbuf list that can     lead to double free. A local, unprivileged user able to     set the HDLC line discipline on the tty device could     use this flaw to increase their privileges on the     system.(CVE-2017-2636)

  - A flaw was found that can be triggered in     keyring_search_iterator in keyring.c if type-i1/4zmatch     is NULL. A local user could use this flaw to crash the     system or, potentially, escalate their     privileges.(CVE-2017-2647)

  - A race condition leading to a NULL pointer dereference     was found in the Linux kernel's Link Layer Control     implementation. A local attacker with access to ping     sockets could use this flaw to crash the     system.(CVE-2017-2671)

  - A vulnerability was found in the Linux kernel in     'tmpfs' file system. When file permissions are modified     via 'chmod' and the user is not in the owning group or     capable of CAP_FSETID, the setgid bit is cleared in     inode_change_ok(). Setting a POSIX ACL via 'setxattr'     sets the file permissions as well as the new ACL, but     doesn't clear the setgid bit in a similar way this     allows to bypass the check in 'chmod'.(CVE-2017-5551)

  - The do_shmat function in ipc/shm.c in the Linux kernel,     through 4.9.12, does not restrict the address     calculated by a certain rounding operation. This allows     privileged local users to map page zero and,     consequently, bypass a protection mechanism that exists     for the mmap system call. This is possible by making     crafted shmget and shmat system calls in a privileged     context.(CVE-2017-5669)

  - A vulnerability was found in the Linux kernel where     having malicious IP options present would cause the     ipv4_pktinfo_prepare() function to drop/free the dst.
    This could result in a system crash or possible     privilege escalation.(CVE-2017-5970)

  - It was reported that with Linux kernel, earlier than     version v4.10-rc8, an application may trigger a BUG_ON     in sctp_wait_for_sndbuf if the socket tx buffer is     full, a thread is waiting on it to queue more data, and     meanwhile another thread peels off the association     being used by the first thread.(CVE-2017-5986)

  - It was found that the original fix for CVE-2016-6786     was incomplete. There exist a race between two     concurrent sys_perf_event_open() calls when both try     and move the same pre-existing software group into a     hardware context.(CVE-2017-6001)

  - A use-after-free flaw was found in the way the Linux     kernel's Datagram Congestion Control Protocol (DCCP)     implementation freed SKB (socket buffer) resources for     a DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO     option is set on the socket. A local, unprivileged user     could use this flaw to alter the kernel memory,     allowing them to escalate their privileges on the     system.(CVE-2017-6074)

  - A flaw was found in the Linux kernel's handling of     packets with the URG flag. Applications using the     splice() and tcp_splice_read() functionality could     allow a remote attacker to force the kernel to enter a     condition in which it could loop     indefinitely.(CVE-2017-6214)

  - The hashbin_delete function in net/irda/irqueue.c in     the Linux kernel improperly manages lock dropping,     which allows local users to cause a denial of service     (deadlock) via crafted operations on IrDA     devices.(CVE-2017-6348)

  - It was found that the code in net/sctp/socket.c in the     Linux kernel through 4.10.1 does not properly restrict     association peel-off operations during certain wait     states, which allows local users to cause a denial of     service (invalid unlock and double free) via a     multithreaded application. This vulnerability was     introduced by CVE-2017-5986 fix (commit     2dcab5984841).(CVE-2017-6353)

  - The keyring_search_aux function in     security/keys/keyring.c in the Linux kernel allows     local users to cause a denial of service via a     request_key system call for the 'dead' key     type.(CVE-2017-6951)

  - The sg_ioctl function in drivers/scsi/sg.c in the Linux     kernel allows local users to cause a denial of service     (stack-based buffer overflow) or possibly have     unspecified other impacts via a large command size in     an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds     write access in the sg_write function.(CVE-2017-7187)

  - In was found that in the Linux kernel, in     vmw_surface_define_ioctl() function in     'drivers/gpu/drm/vmwgfx/vmwgfx_surface.c' file, a     'num_sizes' parameter is assigned a user-controlled     value which is not checked if it is zero. This is used     in a call to kmalloc() and later leads to dereferencing     ZERO_SIZE_PTR, which in turn leads to a GPF and     possibly to a kernel panic.(CVE-2017-7261)

  - An out-of-bounds write vulnerability was found in the     Linux kernel's vmw_surface_define_ioctl() function, in     the 'drivers/gpu/drm/vmwgfx/vmwgfx_surface.c' file. Due     to the nature of the flaw, privilege escalation cannot     be fully ruled out, although we believe it is     unlikely.(CVE-2017-7294)

  - It was found that the packet_set_ring() function of the     Linux kernel's networking implementation did not     properly validate certain block-size data. A local     attacker with CAP_NET_RAW capability could use this     flaw to trigger a buffer overflow, resulting in the     crash of the system. Due to the nature of the flaw,     privilege escalation cannot be fully ruled     out.(CVE-2017-7308)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Missing check in fs/inode.c:inode_init_owner() does not     clear SGID bit on non-directories for     non-members.(CVE-2018-13405)

  - A null pointer dereference in dccp_write_xmit()     function in net/dccp/output.c in the Linux kernel     allows a local user to cause a denial of service by a     number of certain crafted system calls.(CVE-2018-1130)

  - A flaw was found in the Linux kernel, before 4.16.6     where the cdrom_ioctl_media_changed function in     drivers/cdrom/cdrom.c allows local attackers to use a     incorrect bounds check in the CDROM driver     CDROM_MEDIA_CHANGED ioctl to read out kernel     memory.(CVE-2018-10940)

  - The madvise_willneed function in the Linux kernel     allows local users to cause a denial of service     (infinite loop) by triggering use of MADVISE_WILLNEED     for a DAX mapping.(CVE-2017-18208)

  - fuse-backed file mmap-ed onto process cmdline arguments     causes denial of service.(CVE-2018-1120)

  - Memory leak in the sas_smp_get_phy_events function in     drivers/scsi/libsas/sas_expander.c in the Linux kernel     allows local users to cause a denial of service (kernel     memory exhaustion) via multiple read accesses to files     in the /sys/class/sas_phy directory.(CVE-2018-7757)

  - A vulnerability was found in the Linux kernel's     kernel/events/core.c:perf_cpu_time_max_percent_handler(     ) function. Local privileged users could exploit this     flaw to cause a denial of service due to integer     overflow or possibly have unspecified other     impact.(CVE-2017-18255)

  - A flaw was found in the Linux kernel in the way a local     user could create keyrings for other users via keyctl     commands. This may allow an attacker to set unwanted     defaults, a denial of service, or possibly leak keyring     information between users.(CVE-2017-18270)

  - The mm subsystem in the Linux kernel through 4.10.10     does not properly enforce the CONFIG_STRICT_DEVMEM     protection mechanism, which allows local users to read     or write to kernel memory locations in the first     megabyte (and bypass slab-allocation access     restrictions) via an application that opens the     /dev/mem file, related to arch/x86/mm/init.c and     drivers/char/mem.c.(CVE-2017-7889)

  - The code in the drivers/scsi/libsas/sas_scsi_host.c     file in the Linux kernel allow a physically proximate     attacker to cause a memory leak in the ATA command     queue and, thus, denial of service by triggering     certain failure conditions.(CVE-2018-10021)

  - A flaw was found in the Linux kernel's client-side     implementation of the cifs protocol. This flaw allows     an attacker controlling the server to kernel panic a     client which has the CIFS server     mounted.(CVE-2018-1066)

  - A flaw was found in the alarm_timer_nsleep() function     in kernel/time/alarmtimer.c in the Linux kernel. The     ktime_add_safe() function is not used and an integer     overflow can happen causing an alarm not to fire or     possibly a denial-of-service if using a large relative     timeout.(CVE-2018-13053)

  - An issue was discovered in the XFS filesystem in     fs/xfs/libxfs/xfs_attr_leaf.c in the Linux kernel. A     NULL pointer dereference may occur for a corrupted xfs     image after xfs_da_shrink_inode() is called with a NULL     bp. This can lead to a system crash and a denial of     service.(CVE-2018-13094)

  - A flaw was found in the Linux Kernel in the     ucma_leave_multicast() function in     drivers/infiniband/core/ucma.c which allows access to a     certain data structure after freeing it in     ucma_process_join(). This allows an attacker to cause a     use-after-free bug and to induce kernel memory     corruption, leading to a system crash or other     unspecified impact. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2018-14734)

  - A race condition in the store_int_with_restart()     function in arch/x86/kernel/cpu/mcheck/mce.c in the     Linux kernel allows local users to cause a denial of     service (panic) by leveraging root access to write to     the check_interval file in a     /sys/devices/system/machinecheck/machinecheck (cpu     number) directory.(CVE-2018-7995)

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - A flaw was found in the Linux kernel in the way a local     user could create keyrings for other users via keyctl     commands. This may allow an attacker to set unwanted     defaults, a denial of service, or possibly leak keyring     information between users.(CVE-2017-18270)

  - A null pointer dereference in dccp_write_xmit()     function in net/dccp/output.c in the Linux kernel     allows a local user to cause a denial of service by a     number of certain crafted system calls.(CVE-2018-1130)

  - A flaw was found in the Linux kernel, before 4.16.6     where the cdrom_ioctl_media_changed function in     drivers/cdrom/cdrom.c allows local attackers to use a     incorrect bounds check in the CDROM driver     CDROM_MEDIA_CHANGED ioctl to read out kernel     memory.(CVE-2018-10940)

According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - In the Linux kernel before 4.13.5, a local user could     create keyrings for other users via keyctl commands,     setting unwanted defaults or causing a denial of     service.(CVE-2017-18270)

  - ** DISPUTED ** Linux Kernel version 3.18 to 4.16     incorrectly handles an SG_IO ioctl on /dev/sg0 with     dxfer_direction=SG_DXFER_FROM_DEV and an empty 6-byte     cmdp. This may lead to copying up to 1000 kernel heap     pages to the userspace. This has been fixed upstream in     https://github.com/torvalds/linux/commit/a45b599ad808c3     c982fdcdc12b0b8611c2f92824 already. The problem has     limited scope, as users don't usually have permissions     to access SCSI devices. On the other hand, e.g. the     Nero user manual suggests doing `chmod o+r+w /dev/sg*`     to make the devices accessible.(CVE-2018-1000204)

  - A flaw was found affecting the Linux kernel before     version 4.17. By mmap()ing a FUSE-backed file onto a     process's memory containing command line arguments (or     environment strings), an attacker can cause utilities     from psutils or procps (such as ps, w) or any other     program which makes a read() call to the     /proc/pid/cmdline (or /proc/pid/environ) files to block     indefinitely (denial of service) or for some controlled     time (as a synchronization primitive for other     attacks).(CVE-2018-1120)

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2018-1062 advisory.

  - drivers/firewire/net.c in the Linux kernel before 4.8.7, in certain unusual hardware configurations,     allows remote attackers to execute arbitrary code via crafted fragmented packets. (CVE-2016-8633)

  - The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel through 4.5.2 does not     properly randomize the legacy base address, which makes it easier for local users to defeat the intended     restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or     setgid program, by disabling stack-consumption resource limits. (CVE-2016-3672)

  - The prepare_vmcs02 function in arch/x86/kvm/vmx.c in the Linux kernel through 4.13.3 does not ensure that     the CR8-load exiting and CR8-store exiting L0 vmcs02 controls exist in cases where L1 omits the use     TPR shadow vmcs12 control, which allows KVM L2 guest OS users to obtain read and write access to the     hardware CR8 register. (CVE-2017-12154)

  - The bio_map_user_iov and bio_unmap_user functions in block/bio.c in the Linux kernel before 4.13.8 do     unbalanced refcounting when a SCSI I/O vector has small consecutive buffers belonging to the same page.
    The bio_add_pc_page function merges them into one, but the page reference is never dropped. This causes a     memory leak and possible system lockup (exploitable against the host OS by a guest OS user, if a SCSI disk     is passed through to a virtual machine) due to an out-of-memory condition. (CVE-2017-12190)

  - The Linux Kernel 2.6.32 and later are affected by a denial of service, by flooding the diagnostic port     0x80 an exception can be triggered leading to a kernel panic. (CVE-2017-1000407)

  - The dccp_disconnect function in net/dccp/proto.c in the Linux kernel through 4.14.3 allows local users to     gain privileges or cause a denial of service (use-after-free) via an AF_UNSPEC connect system call during     the DCCP_LISTEN state. (CVE-2017-8824)

  - The move_pages system call in mm/migrate.c in the Linux kernel before 4.12.9 doesn't check the effective     uid of the target process, enabling a local attacker to learn the memory layout of a setuid executable     despite ASLR. (CVE-2017-14140)

  - The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel     through 4.10.6 does not validate addition of certain levels data, which allows local users to trigger an     integer overflow and out-of-bounds write, and cause a denial of service (system hang or crash) or possibly     gain privileges, via a crafted ioctl call for a /dev/dri/renderD* device. (CVE-2017-7294)

  - In all Qualcomm products with Android releases from CAF using the Linux kernel, during DMA allocation, due     to wrong data type of size, allocation size gets truncated which makes allocation succeed when it should     fail. (CVE-2017-9725)

  - A flaw was found in the hugetlb_mcopy_atomic_pte function in mm/hugetlb.c in the Linux kernel before 4.13.
    A superfluous implicit page unlock for VM_SHARED hugetlbfs mapping could trigger a local denial of service     (BUG). (CVE-2017-15127)

  - A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel before     4.14.11. The function get_net_ns_by_id() in net/core/net_namespace.c does not check for the net::count     value after it has found a peer network in netns_ids idr, which could lead to double free and memory     corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption     on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully     ruled out, although it is thought to be unlikely. (CVE-2017-15129)

  - Race condition in the ALSA subsystem in the Linux kernel before 4.13.8 allows local users to cause a     denial of service (use-after-free) or possibly have unspecified other impact via crafted /dev/snd/seq     ioctl calls, related to sound/core/seq/seq_clientmgr.c and sound/core/seq/seq_ports.c. (CVE-2017-15265)

  - The __netlink_deliver_tap_skb function in net/netlink/af_netlink.c in the Linux kernel through 4.14.4,     when CONFIG_NLMON is enabled, does not restrict observations of Netlink messages to a single net     namespace, which allows local users to obtain sensitive information by leveraging the CAP_NET_ADMIN     capability to sniff an nlmon interface for all Netlink activity on the system. (CVE-2017-17449)

  - The usb_destroy_configuration function in drivers/usb/core/config.c in the USB core subsystem in the Linux     kernel through 4.14.5 does not consider the maximum number of configurations and interfaces before     attempting to release resources, which allows local users to cause a denial of service (out-of-bounds     write access) or possibly have unspecified other impact via a crafted USB device. (CVE-2017-17558)

  - The Linux kernel version 3.3-rc1 and later is affected by a vulnerability lies in the processing of     incoming L2CAP commands - ConfigRequest, and ConfigResponse messages. This info leak is a result of     uninitialized stack variables that may be returned to an attacker in their uninitialized state. By     manipulating the code flows that precede the handling of these configuration messages, an attacker can     also gain some control over which data will be held in the uninitialized stack variables. This can allow     him to bypass KASLR, and stack canaries protection - as both pointers and stack canaries may be leaked in     this manner. Combining this vulnerability (for example) with the previously disclosed RCE vulnerability in     L2CAP configuration parsing (CVE-2017-1000251) may allow an attacker to exploit the RCE against kernels     which were built with the above mitigations. These are the specifics of this vulnerability: In the     function l2cap_parse_conf_rsp and in the function l2cap_parse_conf_req the following variable is declared     without initialization: struct l2cap_conf_efs efs; In addition, when parsing input configuration     parameters in both of these functions, the switch case for handling EFS elements may skip the memcpy call     that will write to the efs variable: ... case L2CAP_CONF_EFS: if (olen == sizeof(efs)) memcpy(&efs;, (void
    *)val, olen); ... The olen in the above if is attacker controlled, and regardless of that if, in both of     these functions the efs variable would eventually be added to the outgoing configuration request that is     being built: l2cap_add_conf_opt(&ptr;, L2CAP_CONF_EFS, sizeof(efs), (unsigned long) &efs;); So by sending a     configuration request, or response, that contains an L2CAP_CONF_EFS element, but with an element length     that is not sizeof(efs) - the memcpy to the uninitialized efs variable can be avoided, and the     uninitialized variable would be returned to the attacker (16 bytes). (CVE-2017-1000410)

  - The acpi_smbus_hc_add function in drivers/acpi/sbshc.c in the Linux kernel through 4.14.15 allows local     users to obtain sensitive address information by reading dmesg data from an SBS HC printk call.
    (CVE-2018-5750)

  - The xc2028_set_config function in drivers/media/tuners/tuner-xc2028.c in the Linux kernel before 4.6     allows local users to gain privileges or cause a denial of service (use-after-free) via vectors involving     omission of the firmware name from a certain data structure. (CVE-2016-7913)

  - An elevation of privilege vulnerability in the kernel v4l2 video driver. Product: Android. Versions:
    Android kernel. Android ID A-34624167. (CVE-2017-13166)

  - The rngapi_reset function in crypto/rng.c in the Linux kernel before 4.2 allows attackers to cause a     denial of service (NULL pointer dereference). (CVE-2017-15116)

  - A non-privileged user is able to mount a fuse filesystem on RHEL 6 or 7 and crash a system if an     application punches a hole in a file that does not end aligned to a page boundary. (CVE-2017-15121)

  - A use-after-free flaw was found in fs/userfaultfd.c in the Linux kernel before 4.13.6. The issue is     related to the handling of fork failure when dealing with event messages. Failure to fork correctly can     lead to a situation where a fork event will be removed from an already freed list of events with     userfaultfd_ctx_put(). (CVE-2017-15126)

  - net/netfilter/nfnetlink_cthelper.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN     capability for new, get, and del operations, which allows local users to bypass intended access     restrictions because the nfnl_cthelper_list data structure is shared across all net namespaces.
    (CVE-2017-17448)

  - The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x     before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption)     or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action.
    (CVE-2017-18017)

  - The dm_get_from_kobject function in drivers/md/dm.c in the Linux kernel before 4.14.3 allow local users to     cause a denial of service (BUG) by leveraging a race condition with __dm_destroy during creation and     removal of DM devices. (CVE-2017-18203)

  - The KVM subsystem in the Linux kernel through 4.13.3 allows guest OS users to cause a denial of service     (assertion failure, and hypervisor hang or crash) via an out-of bounds guest_irq value, related to     arch/x86/kvm/vmx.c and virt/kvm/eventfd.c. (CVE-2017-1000252)

  - The futex_requeue function in kernel/futex.c in the Linux kernel before 4.14.15 might allow attackers to     cause a denial of service (integer overflow) or possibly have unspecified other impact by triggering a     negative wake or requeue value. (CVE-2018-6927)

  - In the Linux kernel 4.12, 3.10, 2.6 and possibly earlier versions a race condition vulnerability exists in     the sound system, this can lead to a deadlock and denial of service condition. (CVE-2018-1000004)
