CVE-2026-20908: Denial of Service in Intel(R) NPU Driver for Windows
Time-of-check time-of-use race condition for the Intel(R) NPU Driver for Windows for all versions within Ring 1: Device Drivers may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a high complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (low) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
AI Analysis
Technical Summary
This vulnerability involves a TOCTOU race condition in the Intel(R) NPU Driver for Windows, which may be exploited by an unprivileged authenticated local adversary to cause a denial of service. The attack complexity is high and does not require user interaction. The vulnerability affects availability with no direct confidentiality or integrity compromise. No vendor advisory or patch information is currently available to confirm remediation status.
Potential Impact
The primary impact is a denial of service condition affecting system availability. Confidentiality is not impacted, and integrity impact is low but limited to availability disruption. There are no subsequent impacts on confidentiality or integrity beyond the availability effect.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary mitigation has been documented at this time.
