the USN-6895-1 advisory.

    It was discovered that the ATA over Ethernet (AoE) driver in the Linux kernel contained a race condition,
    leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service or
    possibly execute arbitrary code. (CVE-2023-6270)

    It was discovered that the HugeTLB file system component of the Linux Kernel contained a NULL pointer
    dereference vulnerability. A privileged attacker could possibly use this to to cause a denial of service.
    (CVE-2024-0841)

    It was discovered that the Open vSwitch implementation in the Linux kernel could overflow its stack during
    recursive action operations under certain conditions. A local attacker could use this to cause a denial of
    service (system crash). (CVE-2024-1151)

    Gui-Dong Han discovered that the software RAID driver in the Linux kernel contained a race condition,
    leading to an integer overflow vulnerability. A privileged attacker could possibly use this to cause a
    denial of service (system crash). (CVE-2024-23307)

    Bai Jiaju discovered that the Xceive XC4000 silicon tuner device driver in the Linux kernel contained a
    race condition, leading to an integer overflow vulnerability. An attacker could possibly use this to cause
    a denial of service (system crash). (CVE-2024-24861)
