CVE-2021-1082

Data disclosure and service interruption via unchecked length

Published Apr 29, 2021 · Updated Aug 3, 2024

Input validation in NVIDIA vGPU Software before 8.7, 11.4, or 12.2 allows local users to read or alter data or interrupt service. The Virtual GPU Manager plugin accepts an input length without validating it before processing the associated data; NVIDIA has not disclosed the input path. Low-privileged local access is required, and the consequences are bounded to data disclosure or alteration and service interruption.
