A flaw was found in the VirGL virtual OpenGL renderer (virglrenderer). The
virgl did not properly initialize memory when allocating a host-backed
memory resource. A malicious guest could use this flaw to mmap from the
guest kernel and read this uninitialized memory from the host, possibly
leading to information disclosure.
