Unity Linux 20.1050e Security Update: kernel (UTSA-2026-101993)

medium Nessus Plugin ID 337283

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-101993 advisory.

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

intel_th: fix device leak on output open()

Make sure to drop the reference taken when looking up the th device during output device open() on errors and on close().

Note that a recent commit fixed the leak in a couple of open() error paths but not all of them, and the reference is still leaking on successful open().

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.

Solution

Update the affected kernel package.
