CVE-2026-47598 · Severity: high · CVSS 7 · Published 2026-09-30

NVIDIA's GPU display driver for Linux contains a race condition in its kernel module that an unprivileged local user can exploit to trigger a use-after-free vulnerability. A successful attack could allow an attacker to execute arbitrary code with elevated privileges, crash the system, or access sensitive data on machines with vulnerable GPU drivers installed.

**Am I affected by CVE-2026-47598?** Check whether you run Nvidia GPU Display Driver for Linux. 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 open-source kernel module's event delivery path, where a race condition between asynchronous event delivery and file close operations can lead to a use-after-free condition. An unprivileged local attacker can trigger this race without elevated privileges, and exploitation may result in kernel code execution, privilege escalation, denial of service, information disclosure, or data tampering depending on attack success.
