NVIDIA GPU Display Driver Linux Memory Permission Bypass

Publication date: 2026-09-30

Last updated on: 2026-09-30

Assigner: NVIDIA Corporation

Description
NVIDIA GPU Display Driver for Linux contains a vulnerability in the kernel mode layer where an unprivileged user can write to read-only memory because the memory's permissions are not preserved. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, denial of service, information disclosure, and data tampering.

Executive Summary

NVIDIA GPU Display Driver for Linux has a flaw where an unprivileged user can write to read-only memory because memory permissions are not preserved. This could allow an attacker to execute arbitrary code, escalate privileges, cause denial of service, disclose information, or tamper with data.

Detection Guidance

This vulnerability involves improper memory permissions in NVIDIA GPU Display Driver for Linux. Detection requires checking driver versions and kernel logs for suspicious activity. Use commands like 'nvidia-smi' to verify driver version and 'dmesg | grep -i nvidia' to inspect kernel logs for errors related to memory access violations.

Impact Analysis

If exploited, this vulnerability could allow an attacker with local access to gain higher privileges, run malicious code, crash the system, steal sensitive data, or modify critical information. Systems using affected NVIDIA GPU drivers are at risk.

Mitigation Strategies

Immediately update the NVIDIA GPU Display Driver to the latest patched version from NVIDIA's official website. Restrict unprivileged user access to GPU resources and monitor system logs for unusual activity. Consider disabling GPU features if not required until the update is applied.
