CVE-2026-47604 · Severity: medium · CVSS 5.5 · Published 2026-09-30

NVIDIA's GPU display driver for Windows and Linux contains a flaw in its kernel-level component that allows a local user to access GPU memory and state belonging to other applications or users. An attacker with local access could read sensitive data from other processes, including cryptographic keys, machine learning models, or other confidential information processed on the GPU.

**How is CVE-2026-47604 attacked?** It is attacked with local access, in device firmware.

**Am I affected by CVE-2026-47604?** 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 kernel mode driver fails to properly authorize access to GPU channel state, allowing a local attacker to read another process's GPU resources without proper permission checks. This is a local privilege escalation attack that requires prior local access and results in information disclosure. The vulnerability affects both Windows and Linux driver variants.
