USN-6819-2 advisory.

    Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel did not properly validate H2C
    PDU data, leading to a null pointer dereference vulnerability. A remote attacker could use this to cause a
    denial of service (system crash). (CVE-2023-6356, CVE-2023-6535, CVE-2023-6536)

    Chenyuan Yang discovered that the RDS Protocol implementation in the Linux kernel contained an out-of-
    bounds read vulnerability. An attacker could use this to possibly cause a denial of service (system
    crash). (CVE-2024-23849)

    It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel, leading to
    a null pointer dereference vulnerability. A privileged local attacker could use this to possibly cause a
    denial of service (system crash). (CVE-2024-24860)
