Doc Text:	A flaw was found in the Intel Neural Processing Unit (NPU) driver. Due to improper resource locking within the device driver, an authenticated local attacker with standard privileges can cause a denial of service (DoS). By executing unprivileged software, an attacker can disrupt driver operations and make the system or device unresponsive.	Story Points:	---

Description OSIDB Bzimport 2026-11-10 20:04:52 UTC

Improper resource locking for the Intel(R) NPU Drivers before version 32.0.100.4778 within Ring 1: Device Drivers may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
