The remote Ubuntu 18.04 ESM / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6625-1 advisory.

    Marek Marczykowski-Grecki discovered that the Xen event channel infrastructure implementation in the     Linux kernel contained a race condition. An attacker in a guest VM could possibly use this to cause a     denial of service (paravirtualized device unavailability). (CVE-2023-34324)

    Zheng Wang discovered a use-after-free in the Renesas Ethernet AVB driver in the Linux kernel during     device removal. A privileged attacker could use this to cause a denial of service (system crash).
    (CVE-2023-35827)

    It was discovered that a race condition existed in the Linux kernel when performing operations with kernel     objects, leading to an out-of-bounds write. A local attacker could use this to cause a denial of service     (system crash) or execute arbitrary code. (CVE-2023-45863)

     discovered that the NFC Controller Interface (NCI) implementation in the Linux kernel did not     properly handle certain memory allocation failure conditions, leading to a null pointer dereference     vulnerability. A local attacker could use this to cause a denial of service (system crash).
    (CVE-2023-46343)

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.
