CVE-2020-8002

Guest-triggered renderer crash via missing compute shader

Published Jan 27, 2020 · Updated Aug 4, 2024

A NULL pointer dereference in vrend_renderer.c in virglrenderer through 0.8.1 allows guest OS users to crash the renderer. Grid-launch command handling dereferences the current compute-shader object without first verifying that the guest supplied a compute shader. Guest OS access is required, and successful exploitation interrupts the renderer without reported confidentiality or integrity impact.
