CVE-2020-8003

Renderer crash via texture allocation double free

Published Jan 27, 2020 · Updated Aug 4, 2024

Double free in virglrenderer 0.8.1 and earlier allows local users to crash the renderer by triggering texture allocation failure. The vrend_renderer_resource_allocated_texture failure path frees a resource structure that remains owned and is later freed again by its caller. Low-privileged local access and a forced texture-allocation failure are required; the documented consequence is availability loss only.
