CVE-2021-1083

Data disclosure and service interruption via unchecked length

Published Apr 29, 2021 · Updated Aug 3, 2024

Improper input validation in NVIDIA vGPU Software 11.x before 11.4 and 12.x before 12.2 allows local users to disclose or alter data. The guest kernel-mode driver and Virtual GPU Manager plugin accept an input length without validating its permitted bounds. Exploitation requires local low-privileged access; NVIDIA does not specify whether denial of service causes a hang, crash, or broader manager outage.
