CVE-2022-34670

Information disclosure or service interruption via integer truncation

Published Dec 30, 2022 · Updated Apr 11, 2025

Integer truncation in affected NVIDIA vGPU Software Linux guest drivers allows local users to disclose data or interrupt service. The kernel-mode layer handler narrows a primitive value to a smaller type without preserving the discarded data, producing a truncation error. An unprivileged local account is required; NVIDIA does not describe the exposed data or the precise service-failure mode.
