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. Una vulnerabilidad de doble liberación en el archivo vrend_renderer.c en virglrenderer versiones hasta 0.8.1, permite a atacantes causar una denegación de servicio al desencadenar un fallo de asignación de textura, porque vrend_renderer_resource_allocated_texture no es un lugar apropiado para una liberación. • https://gitlab.freedesktop.org/virgl/virglrenderer/commit/f9b079ccc319c98499111f66bd654fc9b56cf15f?merge_request_iid=340 https://gitlab.freedesktop.org/virgl/virglrenderer/merge_requests/340 https://gitlab.freedesktop.org/virgl/virglrenderer/merge_requests/340/diffs?commit_id=3320973c9f2068f60cf6613c2811a8824781878a https://gitlab.freedesktop.org/virgl/virglrenderer/merge_requests/340/diffs?commit_id=f9b079ccc319c98499111f66bd654fc9b56cf15f https://lists.debian.org/debian-lts-announce/2022/12/msg00017.html • CWE-415: Double Free •
