CVE-2022-31616

Memory disclosure or service interruption via escape handler

Published Nov 18, 2022 · Updated Apr 29, 2025

Out-of-bounds read in NVIDIA Cloud Gaming Guest Driver 14.1 and earlier allows local users to disclose memory or interrupt service. The nvlddmkm.sys DxgkDdiEscape handler reads beyond the intended buffer while processing attacker-controlled escape input. Local basic-user access on Windows is required; exploitation discloses memory or interrupts the guest system, with no reported data modification.
