CVE-2020-5961

Guest VM service interruption via incomplete failure-path cleanup

Published Mar 12, 2020 · Updated Aug 4, 2024

Incomplete cleanup in the NVIDIA vGPU graphics driver for guest OS allows local users to interrupt their own Linux guest VM. On a failure path, the driver incorrectly cleans up a resource and leaves the guest unable to continue; NVIDIA has not identified the resource, function, or exact interruption mode. Low-privileged local access inside an affected guest is required, and the consequence is confined to that guest's availability.
