CVE-2023-31022

Host crash via kernel NULL-pointer dereference

Published Nov 2, 2023 · Updated Feb 27, 2025

NULL-pointer dereference in the kernel mode layer of NVIDIA GPU Display Driver for Windows and Linux allows local users to crash the host. NVIDIA has not disclosed the affected function, input path, or precise operation that supplies the null pointer. Low-privileged local access is required, and successful exploitation interrupts availability without reported data disclosure or modification.
