NVD Description
Note: Versions mentioned in the description apply only to the upstream virglrenderer package and not the virglrenderer package as distributed by Alpine:3.17.
See How to fix? for Alpine:3.17 relevant fixed versions and status.
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.
