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.
