Unity Linux 20.1070a Security Update: kernel (UTSA-2026-146319)

high Nessus Plugin ID 372533

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-2026-146319 advisory.

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

drm/amdgpu: fix division by zero with invalid uvd dimensions

When width or height is less than 16, width_in_mb or height_in_mb becomes 0, leading to fs_in_mb being 0. This causes a division by zero when calculating num_dpb_buffer in H264 and H264 Perf decode paths.

Add validation to reject frames with width < 16 or height < 16 before performing any calculations that depend on these values.

V2: Format change - move up all vaiable definitions.
V3: Use warn_once to avoid spam.

(cherry picked from commit 3e41d26c70b0a459d041cc19482a226c4b7423cb)

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.
