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

  - In do_epoll_ctl and ep_loop_check_proc of eventpoll.c,     there is a possible use after free due to a logic     error. This could lead to local escalation of privilege     with no additional execution privileges needed. User     interaction is not needed for     exploitation.(CVE-2020-0466)

  - fs/nfsd/nfs3xdr.c in the Linux kernel through 5.10.8,     when there is an NFS export of a subdirectory of a     filesystem, allows remote attackers to traverse to     other parts of the filesystem via READDIRPLUS. NOTE:
    some parties argue that such a subdirectory export is     not intended to prevent this attack see also the     exports(5) no_subtree_check default     behavior.(CVE-2021-3178)

  - An issue was discovered in the Linux kernel through     5.11.3. A kernel pointer leak can be used to determine     the address of the iscsi_transport structure. When an     iSCSI transport is registered with the iSCSI subsystem,     the transport's handle is available to unprivileged     users via the sysfs file system, at     /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When     read, the show_transport_handle function (in     drivers/scsi/scsi_transport_iscsi.c) is called, which     leaks the handle. This handle is actually the pointer     to an iscsi_transport struct in the kernel module's     global variables.(CVE-2021-27363)

  - An issue was discovered in the Linux kernel through     5.11.3. drivers/scsi/scsi_transport_iscsi.c is     adversely affected by the ability of an unprivileged     user to craft Netlink messages.(CVE-2021-27364)

  - A race condition was found in the Linux kernels     implementation of the floppy disk drive controller     driver software. The impact of this issue is lessened     by the fact that the default permissions on the floppy     device (/dev/fd0) are restricted to root. If the     permissions on the device have changed the impact     changes greatly. In the default configuration root (or     equivalent) permissions are required to attack this     flaw.(CVE-2021-20261)

  - In fs/ocfs2/cluster/nodemanager.c in the Linux kernel     before 4.15, local users can cause a denial of service     (NULL pointer dereference and BUG) because a required     mutex is not used.(CVE-2017-18216)

  - The omninet_open function in     drivers/usb/serial/omninet.c in the Linux kernel before     4.10.4 allows local users to cause a denial of service     (tty exhaustion) by leveraging reference count     mishandling.(CVE-2017-8925)

  - A flaw was found in the way memory resources were freed     in the unix_stream_recvmsg function in the Linux kernel     when a signal was pending. This flaw allows an     unprivileged local user to crash the system by     exhausting available memory. The highest threat from     this vulnerability is to system     availability.(CVE-2021-20265)

  - A flaw was found in the JFS filesystem code in the     Linux Kernel which allows a local attacker with the     ability to set extended attributes to panic the system,     causing memory corruption or escalating privileges. The     highest threat from this vulnerability is to     confidentiality, integrity, as well as system     availability.(CVE-2020-27815)

  - An out-of-bounds (OOB) memory access flaw was found in     x25_bind in net/x25/af_x25.c in the Linux kernel     version v5.12-rc5. A bounds check failure allows a     local attacker with a user account on the system to     gain access to out-of-bounds memory, leading to a     system crash or a leak of internal kernel information.
    The highest threat from this vulnerability is to     confidentiality, integrity, as well as system     availability.(CVE-2020-35519)

  - There is a flaw reported in the Linux kernel in     versions before 5.9 in     drivers/gpu/drm/nouveau/nouveau_sgdma.c in     nouveau_sgdma_create_ttm in Nouveau DRM subsystem. The     issue results from the lack of validating the existence     of an object prior to performing operations on the     object. An attacker with a local account with a root     privilege, can leverage this vulnerability to escalate     privileges and execute code in the context of the     kernel.(CVE-2021-20292)

  - In drivers/pci/hotplug/rpadlpar_sysfs.c in the Linux     kernel through 5.11.8, the RPA PCI Hotplug driver has a     user-tolerable buffer overflow when writing a new     device name to the driver from userspace, allowing     userspace to write data to the kernel stack frame     directly. This occurs because add_slot_store and     remove_slot_store mishandle drc_name '\0' termination,     aka CID-cc7a0bb058b8.(CVE-2021-28972)

  - A race condition was discovered in get_old_root in     fs/btrfs/ctree.c in the Linux kernel through 5.11.8. It     allows attackers to cause a denial of service (BUG)     because of a lack of locking on an extent buffer before     a cloning operation, aka     CID-dbcc7d57bffc.(CVE-2021-28964)

  - An issue was discovered in the Linux kernel before     5.11.7. usbip_sockfd_store in     drivers/usb/usbip/stub_dev.c allows attackers to cause     a denial of service (GPF) because the stub-up sequence     has race conditions during an update of the local and     shared status, aka CID-9380afd6df70.(CVE-2021-29265)

  - BPF JIT compilers in the Linux kernel through 5.11.12     have incorrect computation of branch displacements,     allowing them to execute arbitrary code within the     kernel context. This affects     arch/x86/net/bpf_jit_comp.c and     arch/x86/net/bpf_jit_comp32.c.(CVE-2021-29154)

  - The KVM implementation in the Linux kernel through     4.14.7 allows attackers to obtain potentially sensitive     information from kernel memory, aka a write_mmio     stack-based out-of-bounds read, related to     arch/x86/kvm/x86.c and     include/trace/events/kvm.h.(CVE-2017-17741)

  - An issue was discovered in the Linux kernel before     5.11.3 when a webcam device exists. video_usercopy in     drivers/media/v4l2-core/v4l2-ioctl.c has a memory leak     for large arguments, aka     CID-fb18802a338b.(CVE-2021-30002)

  - An issue was discovered in the Linux kernel through     4.17.10. There is an invalid pointer dereference in
    __del_reloc_root() in fs/btrfs/relocation.c when     mounting a crafted btrfs image, related to removing     reloc rb_trees when reloc control has not been     initialized.(CVE-2018-14609)

  - An issue was discovered in     fs/xfs/libxfs/xfs_inode_buf.c in the Linux kernel     through 4.17.3. A denial of service (memory corruption     and BUG) can occur for a corrupted xfs image upon     encountering an inode that is in extent format, but has     more extents than fit in the inode     fork.(CVE-2018-13095)

  - The vmw_gb_surface_define_ioctl function in     drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux     kernel through 4.10.7 does not validate certain levels     data, which allows local users to cause a denial of     service (system hang) via a crafted ioctl call for a     /dev/dri/renderD* device.(CVE-2017-7346)

  - The klsi_105_get_line_state function in     drivers/usb/serial/kl5kusb105.c in the Linux kernel     before 4.9.5 places uninitialized heap-memory contents     into a log entry upon a failure to read the line     status, which allows local users to obtain sensitive     information by reading the log.(CVE-2017-5549)

  - An integer overflow in the uvesafb_setcmap function in     drivers/video/fbdev/uvesafb.c in the Linux kernel     before 4.17.4 could result in local attackers being     able to crash the kernel or potentially elevate     privileges because kmalloc_array is not     used.(CVE-2018-13406)

  - In the Linux kernel before version 4.12, Kerberos 5     tickets decoded when using the RXRPC keys incorrectly     assumes the size of a field. This could lead to the     size-remaining variable wrapping and the data pointer     going over the end of the buffer. This could possibly     lead to memory corruption and possible privilege     escalation.(CVE-2017-7482)

  - drivers/net/usb/rtl8150.c in the Linux kernel 4.9.x     before 4.9.11 interacts incorrectly with the     CONFIG_VMAP_STACK option, which allows local users to     cause a denial of service (system crash or memory     corruption) or possibly have unspecified other impact     by leveraging use of more than one virtual page for a     DMA scatterlist.(CVE-2017-8069)

  - An issue was discovered in the Linux kernel through     5.11.3. Certain iSCSI data structures do not have     appropriate length constraints or checks, and can     exceed the PAGE_SIZE value. An unprivileged user can     send a Netlink message that is associated with iSCSI,     and has a length up to the maximum length of a Netlink     message.(CVE-2021-27365)

  - A flaw was found in the Nosy driver in the Linux     kernel. This issue allows a device to be inserted twice     into a doubly-linked list, leading to a use-after-free     when one of these devices is removed. The highest     threat from this vulnerability is to confidentiality,     integrity, as well as system availability. Versions     before kernel 5.12-rc6 are affected(CVE-2021-3483)

  - An issue was discovered in the FUSE filesystem     implementation in the Linux kernel before 5.10.6, aka     CID-5d069dbe8aaf. fuse_do_getattr() calls     make_bad_inode() in inappropriate situations, causing a     system crash. NOTE: the original fix for this     vulnerability was incomplete, and its incompleteness is     tracked as CVE-2021-28950.(CVE-2020-36322)

  - An out-of-bounds (OOB) memory write flaw was found in     list_devices in drivers/md/dm-ioctl.c in the     Multi-device driver module in the Linux kernel before     5.12. A bound check failure allows an attacker with     special user (CAP_SYS_ADMIN) privilege to gain access     to out-of-bounds memory leading to a system crash or a     leak of internal kernel information. The highest threat     from this vulnerability is to system     availability.(CVE-2021-31916)

  - A vulnerability was found in Linux Kernel, where a     refcount leak in llcp_sock_connect() causing     use-after-free which might lead to privilege     escalations.(CVE-2020-25671)

  - A vulnerability was found in Linux Kernel where     refcount leak in llcp_sock_bind() causing     use-after-free which might lead to privilege     escalations.(CVE-2020-25670)

  - A memory leak vulnerability was found in Linux kernel     in llcp_sock_connect(CVE-2020-25672)

  - The Linux kernel before 5.11.14 has a use-after-free in     cipso_v4_genopt in net/ipv4/cipso_ipv4.c because the     CIPSO and CALIPSO refcounting for the DOI definitions     is mishandled, aka CID-ad5d07f4a9cd. This leads to     writing an arbitrary value.(CVE-2021-33033)

  - Use After Free vulnerability in nfc sockets in the     Linux Kernel before 5.12.4 allows local attackers to     elevate their privileges. In typical configurations,     the issue can only be triggered by a privileged local     user with the CAP_NET_RAW capability.(CVE-2021-23134)

  - A flaw use-after-free in function     hci_sock_bound_ioctl() of the Linux kernel HCI     subsystem was found in the way user detaches bluetooth     dongle or other way triggers unregister bluetooth     device event. A local user could use this flaw to crash     the system or escalate their privileges on the     system.(CVE-2021-3573)

  - An issue was discovered in the Linux kernel through     5.10.11. PI futexes have a kernel stack use-after-free     during fault handling, allowing local users to execute     code in the kernel, aka     CID-34b1a1ce1458.(CVE-2021-3347)

  - A vulnerability was found in Linux kernel where     non-blocking socket in llcp_sock_connect() leads to     leak and eventually hanging-up the     system.(CVE-2020-25673)

  - net/bluetooth/hci_request.c in the Linux kernel through     5.12.2 has a race condition for removal of the HCI     controller.(CVE-2021-32399)

  - 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 double-free memory corruption in the Linux     kernel HCI device initialization subsystem was found in     the way user attach malicious HCI TTY Bluetooth device.
    A local user could use this flaw to crash the system.
    This flaw affects all the Linux kernel versions     starting from 3.13.(CVE-2021-3564)

  - A flaw was found in the CAN BCM networking protocol in     the Linux kernel, where a local attacker can abuse a     flaw in the CAN subsystem to corrupt memory, crash the     system or escalate privileges.(CVE-2021-3609)

  - The ip6gre_err function in net/ipv6/ip6_gre.c in the     Linux kernel allows remote attackers to have     unspecified impact via vectors involving GRE flags in     an IPv6 packet, which trigger an out-of-bounds     access.(CVE-2017-5897)

  - An Out-of-Bounds Read was discovered in     arch/arm/mach-footbridge/personal-pci.c in the Linux     kernel through 5.12.11 because of the lack of a check     for a value that shouldn't be negative, e.g., access to     element -2 of an array, aka     CID-298a58e165e4.(CVE-2021-32078)

  - In the Linux kernel before 4.20.8,     kvm_ioctl_create_device in virt/kvm/kvm_main.c     mishandles reference counting because of a race     condition, leading to a use-after-free.(CVE-2019-6974)

  - In uvc_scan_chain_forward of uvc_driver.c, there is a     possible linked list corruption due to an unusual root     cause. This could lead to local escalation of privilege     in the kernel with no additional execution privileges     needed. User interaction is not needed for     exploitation.(CVE-2020-0404)

  - In create_pinctrl of core.c, there is a possible out of     bounds read due to a use after free. This could lead to     local information disclosure with no additional     execution privileges needed. User interaction is not     needed for exploitation.(CVE-2020-0427)

The remote Oracle Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-5670 advisory.

  - The Broadcom brcmfmac WiFi driver prior to commit a4176ec356c73a46c07c181c6d04039fafa34a9f is vulnerable     to a frame validation bypass. If the brcmfmac driver receives a firmware event frame from a remote source,     the is_wlc_event_frame function will cause this frame to be discarded and unprocessed. If the driver     receives the firmware event frame from the host, the appropriate handler is called. This frame validation     can be bypassed if the bus used is USB (for instance by a wifi dongle). This can allow firmware event     frames from a remote source to be processed. In the worst case scenario, by sending specially-crafted WiFi     packets, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system.
    More typically, this vulnerability will result in denial-of-service conditions. (CVE-2019-9503)

  - There is heap-based buffer overflow in kernel, all versions up to, excluding 5.3, in the marvell wifi chip     driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly     execute arbitrary code. (CVE-2019-14816)

  - A vulnerability was found in Linux Kernel, where a Heap Overflow was found in mwifiex_set_wmm_params()     function of Marvell Wifi Driver. (CVE-2019-14815)

  - There is heap-based buffer overflow in Linux kernel, all versions up to, excluding 5.3, in the marvell     wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or     possibly execute arbitrary code. (CVE-2019-14814)

  - The rds_inc_info_copy function in net/rds/recv.c in the Linux kernel through 4.6.3 does not initialize a     certain structure member, which allows remote attackers to obtain sensitive information from kernel stack     memory by reading an RDS message. (CVE-2016-5244)

  - 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)

  - An issue was discovered in the Linux kernel 3.16 through 5.5.6. set_fdc in drivers/block/floppy.c leads to     a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it,     aka CID-2e90ca68b0d2. (CVE-2020-9383)

  - An issue was discovered in slc_bump in drivers/net/can/slcan.c in the Linux kernel 3.16 through 5.6.2. It     allows attackers to read uninitialized can_frame data, potentially containing sensitive information from     kernel stack memory, if the configuration lacks CONFIG_INIT_STACK_ALL, aka CID-b9258a2cece4.
    (CVE-2020-11494)

  - The vmw_gb_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel     through 4.10.7 does not validate certain levels data, which allows local users to cause a denial of     service (system hang) via a crafted ioctl call for a /dev/dri/renderD* device. (CVE-2017-7346)

  - Insufficient access control in firmware for Intel(R) Ethernet 700 Series Controllers before version 7.0     may allow a privileged user to potentially enable an escalation of privilege, denial of service, or     information disclosure via local access. (CVE-2019-0139)

  - Buffer overflow in firmware for Intel(R) Ethernet 700 Series Controllers before version 7.0 may allow an     unauthenticated user to potentially enable an escalation of privilege via an adjacent access.
    (CVE-2019-0140)

  - A memory leak in the mwifiex_pcie_alloc_cmdrsp_buf() function in     drivers/net/wireless/marvell/mwifiex/pcie.c in the Linux kernel through 5.3.11 allows attackers to cause a     denial of service (memory consumption) by triggering mwifiex_map_pci_memory() failures, aka CID-     db8fd2cde932. (CVE-2019-19056)

  - In the Linux kernel before 5.3.7, there is a use-after-free bug that can be caused by a malicious USB     device in the drivers/usb/misc/adutux.c driver, aka CID-44efc269db79. (CVE-2019-19523)

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 :

  - An information-leak vulnerability was found in the     kernel when it truncated a file to a smaller size which     consisted of an inline extent that was compressed. The     data between the new file size and the old file size     was not discarded and the number of bytes used by the     inode were not correctly decremented, which gave the     wrong report for callers of the stat(2) syscall. This     wasted metadata space and allowed for the truncated     data to be leaked, and data corruption or loss to     occur. A caller of the clone ioctl could exploit this     flaw by using only standard file-system operations     without root access to read the truncated     data.(CVE-2015-8374i1/4%0

  - crypto/pcrypt.c in the Linux kernel, before 4.14.13,     mishandles freeing instances, allowing a local user     able to access the AF_ALG-based AEAD interface     (CONFIG_CRYPTO_USER_API_AEAD) and pcrypt     (CONFIG_CRYPTO_PCRYPT) to cause a denial of service     (kfree of an incorrect pointer) or possibly have     unspecified other impact by executing a crafted     sequence of system calls. Due to the nature of the     flaw, privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2017-18075i1/4%0

  - An elevation of privilege vulnerability in the Qualcomm     Wi-Fi driver could enable a local malicious application     to execute arbitrary code within the context of the     kernel. This issue is rated as High because it first     requires compromising a privileged process. Product:
    Android. Versions: N/A. Android ID: A-32835279.
    References: QC-CR#1096945.(CVE-2017-0523i1/4%0

  - The saa7164_bus_get function in     drivers/media/pci/saa7164/saa7164-bus.c in the Linux     kernel through 4.10.14 allows local users to cause a     denial of service (out-of-bounds array access) or     possibly have unspecified other impact by changing a     certain sequence-number value, aka a 'double fetch'     vulnerability.(CVE-2017-8831i1/4%0

  - A flaw was found in the way the Linux kernel's splice()     system call validated its parameters. On certain file     systems, a local, unprivileged user could use this flaw     to write past the maximum file size, and thus crash the     system.(CVE-2014-7822i1/4%0

  - The vc4_get_bcl function in     drivers/gpu/drm/vc4/vc4_gem.c in the VideoCore DRM     driver in the Linux kernel before 4.9.7 does not set an     errno value upon certain overflow detections allowing     local users to cause a denial of service (incorrect     pointer dereference and OOPS) via inconsistent size     values in a VC4_SUBMIT_CL ioctl call.(CVE-2017-5577i1/4%0

  - In fs/ocfs2/cluster/nodemanager.c in the Linux kernel     before 4.15, local users can cause a denial of service     (NULL pointer dereference and BUG) because a required     mutex is not used.(CVE-2017-18216i1/4%0

  - A race condition issue leading to a use-after-free flaw     was found in the way the raw packet sockets     implementation in the Linux kernel networking subsystem     handled synchronization while creating the TPACKET_V3     ring buffer. A local user able to open a raw packet     socket (requires the CAP_NET_RAW capability) could use     this flaw to elevate their privileges on the     system.(CVE-2016-8655i1/4%0

  - An exploitable memory corruption flaw was found in the     Linux kernel. The append path can be erroneously     switched from UFO to non-UFO in ip_ufo_append_data()     when building an UFO packet with MSG_MORE option. If     unprivileged user namespaces are available, this flaw     can be exploited to gain root     privileges.(CVE-2017-1000112i1/4%0

  - A security flaw was found in the Linux kernel in a way     that the cleancache subsystem clears an inode after the     final file truncation (removal). The new file created     with the same inode may contain leftover pages from     cleancache and the old file data instead of the new     one.(CVE-2018-16862i1/4%0

  - arch/arm64/ include /asm/pgtable.h in the Linux kernel     before 3.15-rc5-next-20140519, as used in Android     before 2016-07-05 on Nexus 5X and 6P devices,     mishandles execute-only pages, which allows attackers     to gain privileges via a crafted application, aka     Android internal bug 28557020.(CVE-2014-9803i1/4%0

  - A heap-buffer overflow vulnerability was found in the     arcmsr_iop_message_xfer() function in     'drivers/scsi/arcmsr/arcmsr_hba.c' file in the Linux     kernel through 4.8.2. The function does not restrict a     certain length field, which allows local users to gain     privileges or cause a denial of service via an     ARCMSR_MESSAGE_WRITE_WQBUFFER control code. This can     potentially cause kernel heap corruption and arbitrary     kernel code execution.(CVE-2016-7425i1/4%0

  - An issue was discovered in the Linux kernel before     4.18.11. The ipddp_ioctl function in     drivers/net/appletalk/ipddp.c allows local users to     obtain sensitive kernel address information by     leveraging CAP_NET_ADMIN to read the ipddp_route dev     and next fields via an SIOCFINDIPDDPRT ioctl     call.(CVE-2018-20511i1/4%0

  - A memory leak in the irda_bind function in     net/irda/af_irda.c in the Linux kernel, through 4.16,     allows local users to cause a denial of service due to     a memory consumption by repeatedly binding an AF_IRDA     socket.(CVE-2018-6554i1/4%0

  - sound/core/timer.c in the Linux kernel before 4.4.1     employs a locking approach that does not consider slave     timer instances, which allows local users to cause a     denial of service (race condition, use-after-free, and     system crash) via a crafted ioctl     call.(CVE-2016-2547i1/4%0

  - Buffer overflow in the complete_emulated_mmio function     in arch/x86/kvm/x86.c in the Linux kernel before 3.13.6     allows guest OS users to execute arbitrary code on the     host OS by leveraging a loop that triggers an invalid     memory copy affecting certain cancel_work_item     data.(CVE-2014-0049i1/4%0

  - An issue was discovered in the F2FS filesystem code in     the Linux kernel in fs/f2fs/inode.c. A denial of     service due to a slab out-of-bounds read can occur for     a crafted f2fs filesystem image in which FI_EXTRA_ATTR     is set in an inode.(CVE-2018-13098i1/4%0

  - 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-2017-5970i1/4%0

  - In the Linux kernel's vmw_gb_surface_define_ioctl()     function, in 'drivers/gpu/drm/vmwgfx/vmwgfx_surface.c'     file, a 'req-i1/4zmip_levels' is a user-controlled value     which is later used as a loop count limit. This allows     local unprivileged user to cause a denial of service by     a kernel lockup via a crafted ioctl call for a     '/dev/dri/renderD*' device.(CVE-2017-7346i1/4%0

  - It was found that the NFSv4 server in the Linux kernel     did not properly validate layout type when processing     NFSv4 pNFS LAYOUTGET and GETDEVICEINFO operands. A     remote attacker could use this flaw to soft-lockup the     system and thus cause denial of     service.(CVE-2017-8797i1/4%0
