The remote Ubuntu 22.04 LTS / 23.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6724-1 advisory.

    Pratyush Yadav discovered that the Xen network backend implementation in the Linux kernel did not properly     handle zero length data request, leading to a null pointer dereference vulnerability. An attacker in a     guest VM could possibly use this to cause a denial of service (host domain crash). (CVE-2023-46838)

    It was discovered that the Habana's AI Processors driver in the Linux kernel did not properly initialize     certain data structures before passing them to user space. A local attacker could use this to expose     sensitive information (kernel memory). (CVE-2023-50431)

    It was discovered that the device mapper driver in the Linux kernel did not properly validate target size     during certain memory allocations. A local attacker could use this to cause a denial of service (system     crash). (CVE-2023-52429, CVE-2024-23851)

    It was discovered that the CIFS network file system implementation in the Linux kernel did not properly     validate certain SMB messages, leading to an out-of-bounds read vulnerability. An attacker could use this     to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2023-6610)

    Yang Chaoming discovered that the KSMBD implementation in the Linux kernel did not properly validate     request buffer sizes, leading to an out-of-bounds read vulnerability. An attacker could use this to cause     a denial of service (system crash) or possibly expose sensitive information. (CVE-2024-22705)

    Chenyuan Yang discovered that the btrfs file system in the Linux kernel did not properly handle read     operations on newly created subvolumes in certain conditions. A local attacker could use this to cause a     denial of service (system crash). (CVE-2024-23850)

    Several security issues were discovered in the Linux kernel. An attacker could possibly use these to     compromise the system. This update corrects flaws in the following subsystems:

    - Android drivers;

    - Userspace I/O drivers;

    - F2FS file system;

    - SMB network file system;

    - Networking core; (CVE-2023-52434, CVE-2023-52436, CVE-2023-52435, CVE-2023-52439, CVE-2023-52438)

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.
