The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7455-1 advisory.

    Jann Horn discovered that the watch_queue event notification subsystem in the Linux kernel contained an     out-of-bounds write vulnerability. A local attacker could use this to cause a denial of service (system     crash) or escalate their privileges. (CVE-2022-0995)

    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:

    - Network drivers;

    - File systems infrastructure;

    - NTFS3 file system;

    - Ethernet bridge;

    - Ethtool driver;

    - IPv6 networking;

    - Network traffic control;

    - VMware vSockets driver; (CVE-2025-21703, CVE-2024-56651, CVE-2024-50248, CVE-2025-21701, CVE-2024-26837,     CVE-2024-46826, CVE-2025-21993, CVE-2025-21702, CVE-2024-50256, CVE-2025-21756, CVE-2025-21700)

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.
