CVE-2022-42261

Data tampering via unchecked input index

Published Dec 30, 2022 · Updated Apr 11, 2025

Buffer overrun in NVIDIA Virtual GPU Manager 14.3 and earlier allows local users to tamper with or disclose data or interrupt service. The vGPU plugin uses an input index without validating that it remains within the target buffer, permitting an out-of-bounds access. A low-privileged account on an affected hypervisor host is required, and successful exploitation can corrupt or expose data or disrupt the host service.
