Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: virglrenderer (UTSA-2026-093023)

medium Nessus Plugin ID 341221

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-2026-093023 advisory.

A double-free vulnerability in vrend_renderer.c in virglrenderer through 0.8.1 allows attackers to cause a denial of service by triggering texture allocation failure, because vrend_renderer_resource_allocated_texture is not an appropriate place for a free.

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 virglrenderer package.
