CVE-2020-26558, CVE-2021-0129

Researchers at ANSSI discovered vulnerabilities in the Bluetooth Passkey authentication method, and in Linux's implementation of it. An attacker within range of two Bluetooth devices while they pair using Passkey authentication could exploit this to obtain the shared secret (Passkey) and then impersonate either of the devices to each other.

CVE-2020-29374

Jann Horn of Google reported a flaw in Linux's virtual memory management. A parent and child process initially share all their memory, but when either writes to a shared page, the page is duplicated and unshared (copy-on-write). However, in case an operation such as vmsplice() required the kernel to take an additional reference to a shared page, and a copy-on-write occurs during this operation, the kernel might have accessed the wrong process's memory. For some programs, this could lead to an information leak or data corruption.

CVE-2020-36322, CVE-2021-28950

The syzbot tool found that the FUSE (filesystem-in-user-space) implementation did not correctly handle a FUSE server returning invalid attributes for a file. A local user permitted to run a FUSE server could use this to cause a denial of service (crash).

The original fix for this introduced a different potential denial of service (infinite loop in kernel space), which has also been fixed.

CVE-2021-3428

Wolfgang Frisch reported a potential integer overflow in the ext4 filesystem driver. A user permitted to mount arbitrary filesystem images could use this to cause a denial of service (crash).

CVE-2021-28971

Vince Weaver reported a bug in the performance event handler for Intel PEBS. A workaround for a hardware bug on Intel CPUs codenamed 'Haswell' and earlier could lead to a NULL pointer dereference. On systems with the affected CPUs, if users are permitted to access performance events, a local user may exploit this to cause a denial of service (crash).

By default, unprivileged users do not have access to performance events, which mitigates this issue. This is controlled by the kernel.perf_event_paranoid sysctl.

CVE-2021-29154

It was discovered that the Extended BPF (eBPF) JIT compiler for x86_64 generated incorrect branch instructions in some cases. On systems where eBPF JIT is enabled, users could exploit this to execute arbitrary code in the kernel.

By default, eBPF JIT is disabled, mitigating this issue.
This is controlled by the net.core.bpf_jit_enable sysctl.

CVE-2021-29265

CVE-2021-30002

Arnd Bergmann and the syzbot tool found a memory leak in the Video4Linux (v4l) subsystem. A local user permitted to access video devices (by default, any member of the 'video' group) could exploit this to cause a denial of service (memory exhaustion).

CVE-2021-31916

Dan Carpenter reported incorrect parameter validation in the device-mapper (dm) subsystem, which could lead to a heap buffer overrun. However, only users with CAP_SYS_ADMIN capability (i.e.
root-equivalent) could trigger this bug, so it did not have any security impact in this kernel version.

CVE-2021-33034

The syzbot tool found a bug in the Bluetooth subsystem that could lead to a use-after-free. A local user could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA 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 :

  - 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.

  - 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.

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

  - Integer signedness error in the oz_hcd_get_desc_cnf function in drivers/staging/ozwpan/ozhcd.c in the     OZWPAN driver in the Linux kernel through 4.0.5 allows remote attackers to cause a denial of service     (system crash) or possibly execute arbitrary code via a crafted packet. (CVE-2015-4001)

  - drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver in the Linux kernel through 4.0.5 does not ensure     that certain length values are sufficiently large, which allows remote attackers to cause a denial of     service (system crash or large loop) or possibly execute arbitrary code via a crafted packet, related to     the (1) oz_usb_rx and (2) oz_usb_handle_ep_data functions. (CVE-2015-4002)

  - The oz_usb_handle_ep_data function in drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver in the Linux     kernel through 4.0.5 allows remote attackers to cause a denial of service (divide-by-zero error and system     crash) via a crafted packet. (CVE-2015-4003)

  - The OZWPAN driver in the Linux kernel through 4.0.5 relies on an untrusted length field during packet     parsing, which allows remote attackers to obtain sensitive information from kernel memory or cause a     denial of service (out-of-bounds read and system crash) via a crafted packet. (CVE-2015-4004)

  - arch/arm64/kernel/sys.c in the Linux kernel before 4.0 allows local users to bypass the 'strict page     permissions' protection mechanism and modify the system-call table, and consequently gain privileges, by     leveraging write access. (CVE-2015-8967)

  - The ecryptfs_privileged_open function in fs/ecryptfs/kthread.c in the Linux kernel before 4.6.3 allows     local users to gain privileges or cause a denial of service (stack memory consumption) via vectors     involving crafted mmap calls for /proc pathnames, leading to recursive pagefault handling. (CVE-2016-1583)

  - In android for MSM, Firefox OS for MSM, QRD Android, with all Android releases from CAF using the Linux     kernel, a buffer overread is observed in nl80211_set_station when user space application sends attribute     NL80211_ATTR_LOCAL_MESH_POWER_MODE with data of size less than 4 bytes (CVE-2017-11089)

  - 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 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 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 non-blocking socket in llcp_sock_connect() leads to leak     and eventually hanging-up the system. (CVE-2020-25673)

  - An issue was discovered in the Linux kernel before 5.10. drivers/infiniband/core/ucma.c has a use-after-     free because the ctx is reached via the ctx_list in some ucma_migrate_id situations where ucma_close is     called, aka CID-f5449e74802c. (CVE-2020-36385)

  - Improper access control in BlueZ may allow an authenticated user to potentially enable information     disclosure via adjacent access. (CVE-2021-0129)

  - 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)

  - A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c.
    This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name     space (CVE-2021-22555)

  - 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)

  - 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)

  - 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)

  - 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)

  - 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)

  - 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)

  - 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)

  - fs/seq_file.c in the Linux kernel 3.16 through 5.13.x before 5.13.4 does not properly restrict seq buffer     allocations, leading to an integer overflow, an Out-of-bounds Write, and escalation to root by an     unprivileged user, aka CID-8cae8cd89f05. (CVE-2021-33909)

  - net/can/bcm.c in the Linux kernel through 5.12.10 allows local users to obtain sensitive information from     kernel stack memory because parts of a data structure are uninitialized. (CVE-2021-34693)

  - 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)

  - 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 use-after-free in function hci_sock_bound_ioctl() of the Linux kernel HCI subsystem was found in the way     user calls ioct HCIUNBLOCKADDR or other way triggers race condition of the call hci_unregister_dev()     together with one of the calls hci_sock_blacklist_add(), hci_sock_blacklist_del(), hci_get_conn_info(),     hci_get_auth_info(). A privileged local user could use this flaw to crash the system or escalate their     privileges on the system. This flaw affects the Linux kernel versions prior to 5.13-rc5. (CVE-2021-3573)
