Mageia 2022-0401: virglrenderer security update
Summary
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)
