(CVE-2017-13695)

  - In the Linux kernel before 4.20.2, kernel/sched/fair.c mishandles leaf cfs_rq's, which allows attackers to     cause a denial of service (infinite loop in update_blocked_averages) or possibly have unspecified other     impact by inducing a high load. (CVE-2018-20784)

  - An issue was discovered in the fd_locked_ioctl function in drivers/block/floppy.c in the Linux kernel     through 4.15.7. The floppy driver will copy a kernel pointer to user memory in response to the FDGETPRM     ioctl. An attacker can send the FDGETPRM ioctl and use the obtained kernel pointer to discover the     location of kernel code and data and bypass kernel security protections such as KASLR. (CVE-2018-7755)

  - In the Linux kernel 5.0.21, mounting a crafted btrfs filesystem image, performing some operations, and     unmounting can lead to a use-after-free in btrfs_queue_work in fs/btrfs/async-thread.c. (CVE-2019-19377)

  - A buffer over-read flaw was found in RH kernel versions before 5.0 in crypto_authenc_extractkeys in     crypto/authenc.c in the IPsec Cryptographic algorithm's module, authenc. When a payload longer than 4     bytes, and is not following 4-byte alignment boundary guidelines, it causes a buffer over-read threat,     leading to a system crash. This flaw allows a local attacker with user privileges to cause a denial of     service. (CVE-2020-10769)

  - 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 race condition accessing file object in the Linux kernel OverlayFS subsystem was found in the way users     do rename in specific way with OverlayFS. A local user could use this flaw to crash the system.
    (CVE-2021-20321)

  - The fix for XSA-365 includes initialization of pointers such that subsequent cleanup code wouldn't use     uninitialized or stale values. This initialization went too far and may under certain conditions also     overwrite pointers which are in need of cleaning up. The lack of cleanup would result in leaking     persistent grants. The leak in turn would prevent fully cleaning up after a respective guest has died,     leaving around zombie domains. All Linux versions having the fix for XSA-365 applied are vulnerable.
    XSA-365 was classified to affect versions back to at least 3.11. (CVE-2021-28688)

  - 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 race condition accessing file object in the Linux kernel OverlayFS subsystem was found in the way users     do rename in specific way with OverlayFS. A local user could use this flaw to crash the system.
    (CVE-2021-20321)

  - The fix for XSA-365 includes initialization of pointers such that subsequent cleanup code wouldn't use     uninitialized or stale values. This initialization went too far and may under certain conditions also     overwrite pointers which are in need of cleaning up. The lack of cleanup would result in leaking     persistent grants. The leak in turn would prevent fully cleaning up after a respective guest has died,     leaving around zombie domains. All Linux versions having the fix for XSA-365 applied are vulnerable.
    XSA-365 was classified to affect versions back to at least 3.11. (CVE-2021-28688)

  - Insufficient control flow management for the Intel(R) 82599 Ethernet Controllers and Adapters may allow an     authenticated user to potentially enable denial of service via local access. (CVE-2021-33061)

  - net/nfc/llcp_sock.c in the Linux kernel before 5.12.10 allows local unprivileged users to cause a denial     of service (NULL pointer dereference and BUG) by making a getsockname call after a certain type of failure     of a bind call. (CVE-2021-38208)

  - A use-after-free flaw was found in the Linux kernel's FUSE filesystem in the way a user triggers write().
    This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in     privilege escalation. (CVE-2022-1011)

  - A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel's filesystem sub-     component. This flaw allows a local attacker with a user privilege to cause a denial of service.
    (CVE-2022-1184)

  - A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This     flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a     leak of internal kernel information. (CVE-2022-1353)

  - The root cause of this vulnerability is that the ioctl$DRM_IOCTL_MODE_DESTROY_DUMB can decrease refcount     of *drm_vgem_gem_object *(created in *vgem_gem_dumb_create*) concurrently, and *vgem_gem_dumb_create *will     access the freed drm_vgem_gem_object. (CVE-2022-1419)

  - A NULL pointer dereference flaw was found in the Linux kernel's X.25 set of standardized network protocols     functionality in the way a user terminates their session using a simulated Ethernet card and continued     usage of this connection. This flaw allows a local user to crash the system. (CVE-2022-1516)

  - Linux Kernel could allow a local attacker to execute arbitrary code on the system, caused by a concurrency     use-after-free flaw in the bad_flp_intr function. By executing a specially-crafted program, an attacker     could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the     system. (CVE-2022-1652)

  - A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged     user to gain root privileges. The bug allows to build several exploit primitives such as kernel address     information leak, arbitrary execution, etc. (CVE-2022-1729)

  - A flaw in Linux Kernel found in nfcmrvl_nci_unregister_dev() in drivers/nfc/nfcmrvl/main.c can lead to use     after free both read or write when non synchronized between cleanup routine and firmware download routine.
    (CVE-2022-1734)

  - A use-after-free flaw was found in the Linux kernel's NFC core functionality due to a race condition     between kobject creation and delete. This vulnerability allows a local attacker with CAP_NET_ADMIN     privilege to leak kernel information. (CVE-2022-1974)

  - There is a sleep-in-atomic bug in /net/nfc/netlink.c that allows an attacker to crash the Linux kernel by     simulating a nfc device from user-space. (CVE-2022-1975)

  - Incomplete cleanup of multi-core shared buffers for some Intel(R) Processors may allow an authenticated     user to potentially enable information disclosure via local access. (CVE-2022-21123)

  - Incomplete cleanup of microarchitectural fill buffers on some Intel(R) Processors may allow an     authenticated user to potentially enable information disclosure via local access. (CVE-2022-21125)

  - Incomplete cleanup in specific special register read operations for some Intel(R) Processors may allow an     authenticated user to potentially enable information disclosure via local access. (CVE-2022-21127)

  - Incomplete cleanup in specific special register write operations for some Intel(R) Processors may allow an     authenticated user to potentially enable information disclosure via local access. (CVE-2022-21166)

  - Improper input validation for some Intel(R) Processors may allow an authenticated user to potentially     cause a denial of service via local access. (CVE-2022-21180)

  - KGDB and KDB allow read and write access to kernel memory, and thus should be restricted during lockdown.
    An attacker with access to a serial port could trigger the debugger so it is important that the debugger     respect the lockdown mode when/if it is triggered. (CVE-2022-21499)

  - usb_8dev_start_xmit in drivers/net/can/usb/usb_8dev.c in the Linux kernel through 5.17.1 has a double     free. (CVE-2022-28388)

  - ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c in the Linux kernel through 5.17.1 has a double free.
    (CVE-2022-28390)

  - The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers     to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag. (CVE-2022-30594)
