CVE-2022-31607

Local privilege escalation via improper input validation

Published Nov 18, 2022 · Updated Apr 29, 2025

Improper input validation in NVIDIA GPU Display Driver for Linux allows local users to escalate privileges or disrupt the system. The nvidia.ko kernel module fails to validate an unspecified input, and NVIDIA has not published the affected function, input path, or resulting memory operation. Basic local capabilities are required; successful exploitation can also tamper with data or disclose limited information.
