CVE-2022-34682

Local denial of service via null-pointer dereference

Published Dec 30, 2022 · Updated Apr 11, 2025

Null-pointer dereference in the Linux kernel-mode driver in NVIDIA vGPU Software allows local users to interrupt service. The kernel-mode layer dereferences a null pointer reachable by an unprivileged user, but NVIDIA has not disclosed the responsible handler or input path. Exploitation requires local low-privileged access to an affected Linux guest or hypervisor and is limited to an availability impact.
