CVE-2025-20622

Local information disclosure via uncleared reused resources

Published Nov 11, 2025 · Updated Nov 11, 2025

Sensitive-data exposure in Intel NPU Driver for Windows before 32.0.100.4023 allows local users to read residual resource data. The driver releases a Ring 3 resource for reuse without clearing its sensitive contents; Intel has not identified the resource type or code path. Exploitation requires an authenticated, unprivileged local user and an additional attack condition, but no user interaction.
