Unity Linux 20.1070e Security Update: kernel (UTSA-2025-990841)

medium Nessus Plugin ID 275040

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-2025-990841 advisory.

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

 drm/amd/display: Initialize get_bytes_per_element's default to 1

 Variables, used as denominators and maybe not assigned to other values, should not be 0. bytes_per_element_y & bytes_per_element_c are initialized by get_bytes_per_element() which should never return 0.

 This fixes 10 DIVIDE_BY_ZERO issues reported by Coverity.

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.
