    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. CVSS 3.1 Base Score 6.5 (Confidentiality, Integrity and     Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:H).

    CVE-2022-21505:
    A bug in the IMA subsystem was discovered which would incorrectly allow kexec to be used when kernel     lockdown was enabled

    CVE-2022-2153:
    A flaw was found in the Linux kernels KVM when attempting to set a SynIC IRQ. This issue makes it     possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This     flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel     oops condition that results in a denial of service.

    CVE-2022-2318:
    There are use-after-free vulnerabilities caused by timer handler in net/rose/rose_timer.c of linux that     allow attackers to crash linux kernel without any privileges.

    CVE-2022-23816:
    A flaw was found in hw. Mis-trained branch predictions for return instructions may allow arbitrary     speculative code execution under certain microarchitecture-dependent conditions.

    CVE-2022-2503:
    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.

    CVE-2022-2586:
    A use-after-free flaw was found in nf_tables cross-table in the net/netfilter/nf_tables_api.c function in     the Linux kernel. This flaw allows a local, privileged attacker to cause a use-after-free problem at the     time of table deletion, possibly leading to local privilege escalation.

    CVE-2022-2588:
    A use-after-free flaw was found in route4_change in the net/sched/cls_route.c filter implementation in the     Linux kernel. This flaw allows a local user to crash the system and possibly lead to a local privilege     escalation problem.

    CVE-2022-26365:
    Linux disk/nic frontends data leaks [This CNA information record relates to multiple CVEs; the text     explains which aspects/vulnerabilities correspond to which CVE.] Linux Block and Network PV device     frontends don't zero memory regions before sharing them with the backend (CVE-2022-26365, CVE-2022-33740).
    Additionally the granularity of the grant table doesn't allow sharing less than a 4K page, leading to     unrelated data residing in the same 4K page as data shared with a backend being accessible by such backend     (CVE-2022-33741, CVE-2022-33742).

    CVE-2022-2639:
    An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of     actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size()     function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This     flaw allows a local user to crash or potentially escalate their privileges on the system.

    CVE-2022-28893:
    The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets     are in the intended state.

    CVE-2022-29581:

    CVE-2022-2959:
    A race condition was found in the Linux kernel's watch queue due to a missing lock in pipe_resize_ring().
    The specific flaw exists within the handling of pipe buffers. The issue results from the lack of proper     locking when performing operations on an object. This flaw allows a local user to crash the system or     escalate their privileges on the system.

    CVE-2022-2978:
    A flaw use after free in the Linux kernel NILFS file system was found in the way user triggers function     security_inode_alloc to fail with following call to function nilfs_mdt_destroy. A local user could use     this flaw to crash the system or potentially escalate their privileges on the system.

    CVE-2022-29900:
    Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution     under certain microarchitecture-dependent conditions.

    CVE-2022-29901:
    Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their     retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can     hijack return instructions to achieve arbitrary speculative code execution under certain     microarchitecture-dependent conditions.

    CVE-2022-32250:
    net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create     user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to     a use-after-free.
