Several vulnerabilities have been discovered in the Linux kernel that
may lead to a privilege escalation, denial of service or information
leaks.

CVE-2022-0494

    The scsi_ioctl() was susceptible to an information leak only
    exploitable by users with CAP_SYS_ADMIN or CAP_SYS_RAWIO
    capabilities.

CVE-2022-0854

    Ali Haider discovered a potential information leak in the DMA
    subsystem. On systems where the swiotlb feature is needed, this
    might allow a local user to read sensitive information.

CVE-2022-1012

    The randomisation when calculating port offsets in the IP
    implementation was enhanced.

CVE-2022-1729

    Norbert Slusarek discovered a race condition in the perf subsystem
    which could result in local privilege escalation to root. The
    default settings in Debian prevent exploitation unless more
    permissive settings have been applied in the
    kernel.perf_event_paranoid sysctl.

CVE-2022-1786

    Kyle Zeng discovered a use-after-free in the io_uring subsystem
    which way result in local privilege escalation to root.

CVE-2022-1789 / CVE-2022-1852

    Yongkang Jia, Gaoning Pan and Qiuhao Li discovered two NULL pointer
    dereferences in KVM's CPU instruction handling, resulting in denial
    of service.

CVE-2022-1966

    Aaron Adams discovered a use-after-free in Netfilter which may
    result in local privilege escalation to root.

CVE-2022-1972

    Ziming Zhang discovered an out-of-bound write in Netfilter which may
    result in local privilege escalation to root.

CVE-2022-1974 / CVE-2022-1975

    Duoming Zhou discovered that the NFC netlink interface was
    suspectible to denial of service.

CVE-2022-21499

    It was discovered that the kernel debugger could be used to bypass
    UEFI Secure Boot restrictions.

CVE-2022-28893

    Felix Fu discovered a use-after-free in the implementation of the
    Remote Procedure Call (SunRPC) protocol, which could in denial of
    service or an information leak.
