"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-001034 advisory.

    The lbs_debugfs_write function in drivers/net/wireless/libertas/debugfs.c in the Linux kernel through
    3.12.1 allows local users to cause a denial of service (OOPS) by leveraging root privileges for a zero-
    length write operation.

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.");
