Unity Linux 20.1070e Security Update: kernel (UTSA-2025-992237)

medium Nessus Plugin ID 280205

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-2025-992237 advisory.

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

 ALSA: hda: Fix Oops by 9.1 surround channel names

 get_line_out_pfx() may trigger an Oops by overflowing the static array with more than 8 channels. This was reported for MacBookPro 12,1 with Cirrus codec.

 As a workaround, extend for the 9.1 channels and also fix the potential Oops by unifying the code paths accessing the same array with the proper size check.

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.
