The remote Ubuntu 16.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5926-1 advisory.

    Kirill Tkhai discovered that the XFS file system implementation in the Linux kernel did not calculate size     correctly when pre-allocating space in some situations. A local attacker could use this to expose     sensitive information. (CVE-2021-4155)

    Lee Jones discovered that a use-after-free vulnerability existed in the Bluetooth implementation in the     Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly     execute arbitrary code. (CVE-2022-20566)

    Duoming Zhou discovered that a race condition existed in the SLIP driver in the Linux kernel, leading to a     null pointer dereference vulnerability. An attacker could use this to cause a denial of service (system     crash). (CVE-2022-41858)

    Tams Koczka discovered that the Bluetooth L2CAP implementation in the Linux kernel did not properly     initialize memory in some situations. A physically proximate attacker could possibly use this to expose     sensitive information (kernel memory). (CVE-2022-42895)

    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 the RNDIS USB driver in the Linux kernel contained an integer overflow     vulnerability. A local attacker with physical access could plug in a malicious USB device to cause a     denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-23559)

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.
