Description Pedro Sampaio 2020-01-30 20:21:04 UTC 
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.
