# Intel NPU driver: improper locking lets a local user crash the system

Link for people: https://infrastack.ai/live/CVE-2026-40705 (this .md is for agents)

The Intel NPU driver before 32.0.100.4778 has improper resource locking in its Ring 1 device driver code. A local, authenticated user with low-complexity access can cause a denial of service, with no confidentiality or integrity impact.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Intel NPU driver version in Device Manager under the neural processing unit device, or with the Intel driver tooling
- Treat any version below `32.0.100.4778` as affected

## Fix

- Intel NPU Drivers `32.0.100.4778` or later

## Timeline

- 2026-11-10T17:22:43+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-40705

## From the sources

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.
