Data disclosure and tampering via out-of-bounds write

Published Dec 30, 2022 · Updated Apr 23, 2025

Out-of-bounds write in NVIDIA vGPU Software 14.2, 13.4, and 11.9 and earlier allows local users to disclose or alter data or interrupt service. The nvidia.ko kernel-mode layer writes beyond an array boundary; NVIDIA has not identified the affected handler or input path. Successful exploitation requires low-privileged local access and can disclose or alter data or interrupt service.
