A flaw was found in the NVIDIA GPU Display Driver for Linux. A local user can exploit this vulnerability by providing crafted input that triggers a format string flaw. Successful exploitation may lead to arbitrary code execution, privilege escalation, a Denial of Service (DoS), or unauthorized disclosure of sensitive data.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

The following CVSS metrics and score provided are preliminary and subject to review.
