CVE-2022-31606

Local kernel compromise via unvalidated DxgkDdiEscape data

Published Nov 18, 2022 · Updated Apr 29, 2025

Out-of-bounds access in NVIDIA Cloud Gaming Guest Driver releases before the August 2022 release allows local users to compromise the Windows kernel. The nvlddmkm.sys DxgkDdiEscape handler fails to validate user-controlled data before accessing kernel memory outside the intended bounds. Basic user capabilities are sufficient; exploitation can disclose kernel data, tamper with data, elevate privileges, or interrupt the system.
