CVE-2025-26402

Local denial of service

Published Nov 11, 2025 · Updated Nov 11, 2025

Protection mechanism failure in Intel NPU Drivers before Linux 1.16.0 and Windows 32.0.100.4023 allows local users to interrupt service. Intel identifies the locus only as Ring 3 user applications and has not published the failed protection, affected operation, or triggering input. An authenticated, unprivileged local user requires no interaction from another user, and the documented consequence is availability loss without confidentiality or integrity impact.
