CVE-2023-31018

Local service interruption via kernel NULL dereference

Published Nov 2, 2023 · Updated Feb 27, 2025

NULL-pointer dereference in the kernel mode layer of NVIDIA vGPU Software Graphics Driver allows local users to interrupt service. The vendor has not disclosed the specific kernel-mode function or malformed input path that triggers the invalid dereference. An unprivileged regular account with local access is sufficient, and the documented consequence is limited to denial of service.
