Name of the Vulnerable Software and Affected Versions Virglrenderer in ChromeOS version 16093.57.0

Description The issue is an out-of-bounds read in Virglrenderer that allows a malicious guest VM to achieve arbitrary address access within the crosvm sandboxed process. This could potentially lead to VM escape via crafted vertex elements data that triggers an out-of-bounds read in util format description.

Recommendations For Virglrenderer in ChromeOS version 16093.57.0, consider restricting access to the util format description function until a patch is available. As a temporary workaround, avoid using crafted vertex elements data in the affected API endpoint. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
