CVE-2022-31618

Denial of service via null-pointer dereference

Published Aug 5, 2022 · Updated Jun 2, 2026

Null-pointer dereference in NVIDIA vGPU Software 11.x, 13.x, and 14.x allows local users to cause a denial of service. The Virtual GPU Manager vGPU plugin dereferences a null pointer, but NVIDIA has not disclosed the triggering input or code path. Exploitation requires low-privileged local access in a Citrix Hypervisor, VMware vSphere, or Red Hat Enterprise Linux KVM deployment and has only a reported availability impact.
