specially crafted virgil resource and then issue a VIRTGPU_EXECBUFFER
ioctl, leading to a denial of service or possible code execution.
(CVE-2022-0135)

A flaw was found in the VirGL virtual OpenGL renderer (virglrenderer). The
virgl did not properly initialize memory when allocating a host-backed

guest kernel and read this uninitialized memory from the host, possibly
leading to information disclosure. (CVE-2022-0175)
