    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)

    Sander Wiebing, Alvise de Faveri Tron, Herbert Bos, and Cristiano Giuffrida discovered that the Linux
    kernel mitigations for the initial Branch History Injection vulnerability (CVE-2022-0001) were
    insufficient for Intel processors. A local attacker could potentially use this to expose sensitive
    information. (CVE-2024-2201)

    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)

    compromise the system. This update corrects flaws in the following subsystems:
