The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-986598 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    smackfs: restrict bytes count in smk_set_cipso()

    Oops, I failed to update subject line.

    From 07571157c91b98ce1a4aa70967531e64b78e8346 Mon Sep 17 00:00:00 2001     Date: Mon, 12 Apr 2021 22:25:06 +0900     Subject: [PATCH] smackfs: restrict bytes count in smk_set_cipso()

    Commit 7ef4c19d245f3dc2 (smackfs: restrict bytes count in smackfs write     functions) missed that count > SMK_CIPSOMAX check applies to only     format == SMK_FIXED24_FMT case.

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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
