CVE-2022-28191

Local service interruption via uncontrolled resource consumption

Published May 17, 2022 · Updated Aug 3, 2024

Resource-consumption flaw in NVIDIA vGPU software 14.0 and earlier allows local users to interrupt the Virtual GPU Manager. The nvidia.ko kernel module permits an unprivileged regular user to trigger uncontrolled resource consumption, but NVIDIA has not disclosed the responsible input path or allocation operation. Successful exploitation exhausts host resources and denies vGPU service without reported confidentiality or integrity impact.
