"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-002003 advisory.

    The UDF filesystem implementation in the Linux kernel before 3.18.2 does not validate certain lengths,
    which allows local users to cause a denial of service (buffer over-read and system crash) via a crafted
    filesystem image, related to fs/udf/inode.c and fs/udf/symlink.c.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
