    It was discovered that the XFS file system implementation in the Linux kernel did not properly perform     metadata validation when mounting certain images. An attacker could use this to specially craft a file     system image that, when mounted, could cause a denial of service (system crash). (CVE-2023-2124)

    Juan Jose Lopez Jaimez, Meador Inge, Simon Scannell, and Nenad Stojanovski discovered that the BPF     verifier in the Linux kernel did not properly mark registers for precision tracking in certain situations,     leading to an out- of-bounds access vulnerability. A local attacker could use this to cause a denial of     service (system crash) or possibly execute arbitrary code. (CVE-2023-2163)

    It was discovered that the SLIMpro I2C device driver in the Linux kernel did not properly validate user-     supplied data in some situations, leading to an out-of-bounds write vulnerability. A privileged attacker     could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
    (CVE-2023-2194)

    It was discovered that the perf subsystem in the Linux kernel contained a use-after-free vulnerability. A     privileged local attacker could possibly use this to cause a denial of service (system crash) or possibly     execute arbitrary code. (CVE-2023-2235)

    Zheng Zhang discovered that the device-mapper implementation in the Linux kernel did not properly handle     locking during table_clear() operations. A local attacker could use this to cause a denial of service     (kernel deadlock). (CVE-2023-2269)

    It was discovered that the ARM Mali Display Processor driver implementation in the Linux kernel did not     properly handle certain error conditions. A local attacker could possibly use this to cause a denial of     service (system crash). (CVE-2023-23004)

    It was discovered that a race condition existed in the TLS subsystem in the Linux kernel, leading to a     use-after-free or a null pointer dereference vulnerability. A local attacker could use this to cause a     denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-28466)

    It was discovered that the DA9150 charger driver in the Linux kernel did not properly handle device     removal, leading to a user-after free vulnerability. A physically proximate attacker could use this to     cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-30772)

    It was discovered that the Ricoh R5C592 MemoryStick card reader driver in the Linux kernel contained a     race condition during module unload, 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-2023-3141)

    Quentin Minster discovered that the KSMBD implementation in the Linux kernel did not properly validate     pointers in some situations, leading to a null pointer dereference vulnerability. A remote attacker could     use this to cause a denial of service (system crash). (CVE-2023-32248)

    It was discovered that the kernel->user space relay implementation in the Linux kernel did not properly     perform certain buffer calculations, leading to an out-of-bounds read vulnerability. A local attacker     could use this to cause a denial of service (system crash) or expose sensitive information (kernel     memory). (CVE-2023-3268)

    It was discovered that the Qualcomm EMAC ethernet driver in the Linux kernel did not properly handle     device removal, leading to a user-after free vulnerability. A physically proximate attacker could use this     to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-33203)

    It was discovered that the BQ24190 charger driver in the Linux kernel did not properly handle device     removal, leading to a user-after free vulnerability. A physically proximate attacker could use this to     cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-33288)

    It was discovered that the video4linux driver for Philips based TV cards in the Linux kernel contained a     race condition during device removal, leading to a use-after-free vulnerability. A physically proximate     attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
    (CVE-2023-35823)

    It was discovered that the SDMC DM1105 PCI device driver in the Linux kernel contained a race condition     during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could     use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-35824)

    It was discovered that the Renesas USB controller driver in the Linux kernel contained a race condition     during device removal, leading to a use- after-free vulnerability. A privileged attacker could use this to     cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-35828)

    It was discovered that the Rockchip Video Decoder IP driver in the Linux kernel contained a race condition     during device removal, leading to a use- after-free vulnerability. A privileged attacker could use this to     cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-35829)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
