A double-free vulnerability in vrendrenderer.c in virglrenderer through 0.8.1 allows attackers to cause a denial of service by triggering texture allocation failure, because vrendrendererresourceallocatedtexture is not an appropriate place for a free.
A NULL pointer dereference in vrendrenderer.c in virglrenderer through 0.8.1 allows attackers to cause a denial of service via commands that attempt to launch a grid without previously providing a Compute Shader (CS).
