Local information disclosure via DxgkDdiEscape handler
Published Dec 30, 2022 · Updated Apr 11, 2025
Information disclosure in NVIDIA vGPU Software Graphics Driver 14.3 and earlier allows local users to obtain sensitive information. The nvlddmkm.sys DxgkDdiEscape handler exposes sensitive information, but NVIDIA has not disclosed the faulty operation or input condition. A regular unprivileged Windows user must invoke the local escape handler; the reported consequence is limited to unauthorized information disclosure.
