Detailsinfo

A vulnerability was found in Intel NPU Drivers and classified as critical. This issue affects some unknown processing of the component Device Drivers. The manipulation with an unknown input leads to a locking vulnerability. Using CWE to declare the problem leads to CWE-667. The product does not properly acquire or release a lock on a resource, leading to unexpected resource state changes and behaviors. Impacted is availability. The summary by CVE is:

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.

It is possible to read the advisory at intel.com. The identification of this vulnerability is CVE-2026-40705 since 04/18/2026. The exploitation is known to be easy. Attacking locally is a requirement. The technical details are unknown and an exploit is not publicly available.
