CVE-2023-0197

Host service crash via guest-triggered NULL dereference

Published Apr 1, 2023 · Updated Feb 11, 2025

NULL-pointer dereference in NVIDIA Virtual GPU Manager 15.1 and earlier allows guest OS users to interrupt the host service. The host-side manager dereferences a NULL pointer after processing malicious input from a guest VM; NVIDIA has not disclosed the specific request handler or input field. A low-privileged guest OS user can trigger the condition across the virtualization boundary, causing availability loss without reported data access or modification.
