    The identifier VDB-211021 was assigned to this vulnerability.(CVE-2022-3524)

    mm/rmap.c in the Linux kernel before 5.19.7 has a use-after-free related to leaf anon_vma double     reuse.(CVE-2022-42703)

    roccat_report_event in drivers/hid/hid-roccat.c in the Linux kernel through 5.19.12 has a race condition     and resultant use-after-free in certain situations where a report is received while copying a report-     value is in progress.(CVE-2022-41850)

    In __hidinput_change_resolution_multipliers of hid-input.c, there is a possible out of bounds write due to     a heap buffer overflow. This could lead to local escalation of privilege with no additional execution     privileges needed. User interaction is not needed for exploitation.(CVE-2021-0512)

    In fs/eventpoll.c, there is a possible use after free. This could lead to local escalation of privilege     with no additional execution privileges needed. User interaction is not needed for     exploitation.(CVE-2021-39634)

    drivers/scsi/stex.c in the Linux kernel through 5.19.9 allows local users to obtain sensitive information     from kernel memory because stex_queuecommand_lck lacks a memset for the PASSTHRU_CMD case.(CVE-2022-40768)

    In xfrm6_tunnel_free_spi of net/ipv6/xfrm6_tunnel.c, there is a possible use after free due to improper     locking. This could lead to local escalation of privilege with System execution privileges needed. User     interaction is not needed for exploitation.(CVE-2020-27066)

    An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race     condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale     TLB entries. This only occurs in situations with VM_PFNMAP VMAs.(CVE-2022-39188)

    An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and     incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted     IRC with nf_conntrack_irc configured.(CVE-2022-2663)

    A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem)     when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to     potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read     and copying it into a socket.(CVE-2022-3028)

    A flaw was found in the Linux kernels driver for the ASIX AX88179_178A-based USB 2.0/3.0 Gigabit     Ethernet Devices. The vulnerability contains multiple out-of-bounds reads and possible out-of-bounds     writes.(CVE-2022-2964)

    A flaw was found in the Linux kernel implementation of proxied virtualized TPM devices. On a system where     virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after-     free and create a situation where it may be possible to escalate privileges on the system.(CVE-2022-2977)

    Dm-verity is used for extending root-of-trust to root filesystems. LoadPin builds on this property to     restrict module/firmware loads to just the trusted root filesystem. Device-mapper table reloads currently     allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass     verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and     unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for     peripherals that do not verify firmware updates. We recommend upgrading past commit     4caae58406f8ceb741603eee460d79bacca9b1b5(CVE-2022-2503)

    A use-after-free flaw was found in the Linux kernels Atheros wireless adapter driver in the way a user     forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local     user to crash or potentially escalate their privileges on the system.(CVE-2022-1679)

    An information leak flaw was found in NFS over RDMA in the net/sunrpc/xprtrdma/rpc_rdma.c in the Linux     Kernel. This flaw allows an attacker with normal user privileges to leak kernel     information.(CVE-2022-0812)
