Unity Linux 20.1050e Security Update: kernel (UTSA-2026-007510)

high Nessus Plugin ID 307185

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-2026-007510 advisory.

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

ASoC: Intel: bytcr_rt5640: Fix invalid quirk input mapping

When an invalid value is passed via quirk option, currently bytcr_rt5640 driver only shows an error message but leaves as is.
This may lead to unepxected results like OOB access.

This patch corrects the input mapping to the certain default value if an invalid value is passed.

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.
