"The remote Ubuntu 22.04 LTS / 24.04 LTS / 26.04 LTS host has packages installed that are affected by multiple
vulnerabilities as referenced in the USN-8626-1 advisory.

    It was discovered that systemd-homed did not properly verify the signature of home records. A local
    attacker could possibly use this issue to add arbitrary system groups to a logged-in user and gain
    elevated privileges. (CVE-2026-16742)

    It was discovered that systemd-machined incorrectly handled certain polkit authorization checks. A local
    attacker could possibly use this issue to terminate arbitrary processes, including privileged ones. This
    issue only affected Ubuntu 26.04 LTS. (CVE-2026-15060)

    It was discovered that systemd-oomd did not properly validate certain IPC requests. A local attacker could
    possibly use this issue to terminate arbitrary processes. (CVE-2026-15059)

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.");
