CVE-2022-34676

Data tampering or service interruption via out-of-bounds read

Published Dec 30, 2022 · Updated Apr 11, 2025

Out-of-bounds read in NVIDIA vGPU Software 14.3 and earlier allows local users to tamper with data or interrupt service. The Linux kernel-mode layer handler reads beyond a buffer boundary, but NVIDIA has not disclosed the triggering input or code path. Low-privilege local access is required; successful exploitation can corrupt data or interrupt the host or guest service, while the exact failure mode remains undisclosed.
