CVE-2026-47603: NVIDIA GPU Display Driver information disclosure in kernel mode driver

CVE-2026-47603 · Severity: medium · CVSS 5.5 · Published 2026-09-30

NVIDIA's GPU display drivers for Windows and Linux contain a flaw in the kernel driver that allows a local user on a system to read GPU state information from other applications or processes. An attacker with local access could gain unauthorized visibility into sensitive computational data or credentials being processed by other programs on the same GPU.

Technologies: Nvidia GPU Display Driver for Linux, Nvidia GPU Display Driver for Windows. Vendors: Nvidia.

Quick answers

No. Junglewise Threat Intelligence has no report of CVE-2026-47603 being exploited in the wild.
How severe is CVE-2026-47603?
Medium severity, with a CVSS score of 5.5, published 30 September 2026.
Which products and versions are affected?
NVIDIA GPU Display Driver for Windows; NVIDIA GPU Display Driver for Linux.
Is there a fix for CVE-2026-47603?
No fixed version is recorded yet. Check the vendor's advisory in the references below. If you run it, Junglewise drafts a mitigation that fits your setup and applies it once you approve, with senior security engineers behind it.
How is CVE-2026-47603 attacked?
It is attacked with local access, in device firmware.
Am I affected by CVE-2026-47603?
Check whether you run Nvidia GPU Display Driver for Linux or Nvidia GPU Display Driver for Windows. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

Technical details

The vulnerability exists in the kernel mode driver's GPU channel state management, where missing authorization checks permit local users to access process GPU memory or state belonging to other processes. Attack requires local access to the affected system. Successful exploitation leads to information disclosure without code execution or privilege escalation.
