CVE-2021-1061

Information disclosure or service interruption via resource race

Published Jan 8, 2021 · Updated Aug 3, 2024

Race condition in NVIDIA Virtual GPU Manager 8.x before 8.6 and 11.x before 11.3 allows local users to disclose data or interrupt service. The vGPU plugin continues using a previously validated resource after a concurrent change makes that validation stale. Exploitation requires low-privileged local access and successful race timing; the resulting impact is limited to information disclosure or service interruption.
