    It was discovered that a use-after-free vulnerability existed in the SGI GRU driver in the Linux kernel. A     local attacker could possibly use this to cause a denial of service (system crash) or possibly execute     arbitrary code. (CVE-2022-3424)

    Gwangun Jung discovered a race condition in the IPv4 implementation in the Linux kernel when deleting     multipath routes, resulting in an out-of-bounds read. An attacker could use this to cause a denial of     service (system crash) or possibly expose sensitive information (kernel memory). (CVE-2022-3435)

    It was discovered that a race condition existed in the Kernel Connection Multiplexor (KCM) socket     implementation in the Linux kernel when releasing sockets in certain situations. A local attacker could     use this to cause a denial of service (system crash). (CVE-2022-3521)

    It was discovered that the Netronome Ethernet driver in the Linux kernel contained a use-after-free     vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly     execute arbitrary code. (CVE-2022-3545)

    It was discovered that the hugetlb implementation in the Linux kernel contained a race condition in some     situations. A local attacker could use this to cause a denial of service (system crash) or expose     sensitive information (kernel memory). (CVE-2022-3623)

    Ziming Zhang discovered that the VMware Virtual GPU DRM driver in the Linux kernel contained an out-of-     bounds write vulnerability. A local attacker could use this to cause a denial of service (system crash).
    (CVE-2022-36280)

    Hyunwoo Kim discovered that the DVB Core driver in the Linux kernel did not properly perform reference     counting in some situations, leading to a use- after-free vulnerability. A local attacker could use this     to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-41218)

    It was discovered that the Intel i915 graphics driver in the Linux kernel did not perform a GPU TLB flush     in some situations. A local attacker could use this to cause a denial of service or possibly execute     arbitrary code. (CVE-2022-4139)

    It was discovered that a race condition existed in the Xen network backend driver in the Linux kernel when     handling dropped packets in certain circumstances. An attacker could use this to cause a denial of service     (kernel deadlock). (CVE-2022-42328, CVE-2022-42329)

    It was discovered that the Atmel WILC1000 driver in the Linux kernel did not properly validate offsets,     leading to an out-of-bounds read vulnerability. An attacker could use this to cause a denial of service     (system crash). (CVE-2022-47520)

    It was discovered that the network queuing discipline implementation in the Linux kernel contained a null     pointer dereference in some situations. A local attacker could use this to cause a denial of service     (system crash). (CVE-2022-47929)

    Jos Oliveira and Rodrigo Branco discovered that the prctl syscall implementation in the Linux kernel did     not properly protect against indirect branch prediction attacks in some situations. A local attacker could     possibly use this to expose sensitive information. (CVE-2023-0045)

    It was discovered that a use-after-free vulnerability existed in the Advanced Linux Sound Architecture     (ALSA) subsystem. A local attacker could use this to cause a denial of service (system crash).
    (CVE-2023-0266)

    Kyle Zeng discovered that the IPv6 implementation in the Linux kernel contained a NULL pointer dereference     vulnerability in certain situations. A local attacker could use this to cause a denial of service (system     crash). (CVE-2023-0394)

    Wei Chen discovered that a race condition existed in the TIPC protocol implementation in the Linux kernel,     leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of     service (system crash). (CVE-2023-1382)

    It was discovered that the Android Binder IPC subsystem in the Linux kernel did not properly validate     inputs in some situations, leading to a use- after-free vulnerability. A local attacker could use this to     cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-20938)

    Kyle Zeng discovered that the class-based queuing discipline implementation in the Linux kernel contained     a type confusion vulnerability in some situations. An attacker could use this to cause a denial of service     (system crash). (CVE-2023-23454)

    Kyle Zeng discovered that the ATM VC queuing discipline implementation in the Linux kernel contained a     type confusion vulnerability in some situations. An attacker could use this to cause a denial of service     (system crash). (CVE-2023-23455)

    It was discovered that the NTFS file system implementation in the Linux kernel did not properly validate     attributes in certain situations, leading to an out-of-bounds read vulnerability. A local attacker could     possibly use this to expose sensitive information (kernel memory). (CVE-2023-26607)

    Wei Chen discovered that the DVB USB AZ6027 driver in the Linux kernel contained a null pointer     dereference when handling certain messages from user space. A local attacker could use this to cause a     denial of service (system crash). (CVE-2023-28328)
