## Affected

- n/a Intel(R) NPU Driver for Windows: all versions

## Description

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.
