The remote Ubuntu 23.04 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6250-1 advisory.

    Stonejiajia, Shir Tamari and Sagi Tzadik discovered that the OverlayFS implementation in the Ubuntu Linux     kernel did not properly perform permission checks in certain situations. A local attacker could possibly     use this to gain elevated privileges. (CVE-2023-2640)

    It was discovered that the IP-VLAN network driver for the Linux kernel did not properly initialize memory     in some situations, leading to an out-of- bounds write vulnerability. An attacker could use this to cause     a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-3090)

    Mingi Cho discovered that the netfilter subsystem in the Linux kernel did not properly validate the status     of a nft chain while performing a lookup by id, leading to a use-after-free vulnerability. An attacker     could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
    (CVE-2023-31248)

    Shir Tamari and Sagi Tzadik discovered that the OverlayFS implementation in the Ubuntu Linux kernel did     not properly perform permission checks in certain situations. A local attacker could possibly use this to     gain elevated privileges. (CVE-2023-32629)

    Ruihan Li discovered that the memory management subsystem in the Linux kernel contained a race condition     when accessing VMAs in certain conditions, leading to a use-after-free vulnerability. A local attacker     could possibly use this to cause a denial of service (system crash) or execute arbitrary code.
    (CVE-2023-3269)

    Querijn Voet discovered that a race condition existed in the io_uring subsystem in the Linux kernel,     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-2023-3389)

    It was discovered that the netfilter subsystem in the Linux kernel did not properly handle some error     conditions, 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-2023-3390)

    Tanguy Dubroca discovered that the netfilter subsystem in the Linux kernel did not properly handle certain     pointer data type, 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-2023-35001)

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.
