An out-of-bounds write issue was found in the VirGL virtual OpenGL renderer (virglrenderer). This flaw allows a malicious guest to create a 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 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. (CVE-2022-0175)
