The util_format_is_pure_uint function in vrend_renderer.c in Virgil 3d project (aka virglrenderer) 0.6.0 and earlier allows local guest OS users to cause a denial of service (NULL pointer dereference) via a crafted VIRGL_CCMD_CLEAR command.

This update for virglrenderer fixes the following issues :
