CVE-2022-34666

Local denial of service via kernel null dereference

Published Nov 10, 2022 · Updated May 1, 2025

NVIDIA GPU Display Driver for Windows and Linux allows local users with basic capabilities to cause denial of service via the kernel mode layer. The kernel-mode driver dereferences a null pointer when processing a reachable request, causing the driver or host kernel to fail. The attacker needs local basic capabilities and no user interaction; the documented consequence is service interruption, with no stated confidentiality or integrity impact.
