CVE-2026-47548
Description
A flaw was found in the NVIDIA GPU display driver. A local user can exploit an out-of-bounds write vulnerability within the kernel mode layer to corrupt system memory. Successful exploitation could allow an attacker to achieve arbitrary code execution with elevated kernel privileges, trigger a Denial of Service (DoS) by crashing the system, modify data, or disclose sensitive information.
Statement
Red Hat rates the impact of this vulnerability as Important rather than Moderate because a local authenticated user could corrupt kernel-space memory, resulting in complete system compromise or an unrecoverable system crash. Exploitation requires direct local execution privileges on a host equipped with affected NVIDIA graphics hardware and proprietary drivers, preventing remote or unauthenticated exploitation. Default Red Hat Enterprise Linux installations are not affected as the shipped driver packages do not contain the vulnerable code.
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.
