CVE-2026-47518
Description
A flaw was found in the NVIDIA GPU Display Driver. An incorrect permission assignment for a critical resource in a secure microcontroller component allows an attacker with privileged local access to modify restricted protected memory. This vulnerability may allow an attacker to achieve arbitrary code execution and further privilege escalation on the host system.
Statement
On Red Hat Enterprise Linux systems deploying proprietary NVIDIA GPU display drivers, this vulnerability is rated as Moderate impact because exploitation requires pre-existing local administrative privileges and satisfies complex execution conditions, preventing remote or unprivileged abuse. Although tampering with restricted microcontroller memory can lead to code execution and system compromise, an attacker must already possess elevated permissions on the host to interact with the vulnerable hardware component. Standard installations without dedicated NVIDIA hardware or systems running open-source drivers are not affected by this flaw.
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.
