Am I affected by CVE-2026-40705?

Check whether you run Intel NPU Driver for Linux or Intel NPU Driver for Windows at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

CVE-2026-40705: Intel NPU Driver improper resource locking denial of service

CVE-2026-40705 · Severity: info · Published 2026-11-10

Intel's NPU (Neural Processing Unit) Drivers contain a resource locking flaw that can cause a system to become unresponsive or crash. An authenticated user on the local system can trigger this vulnerability with a simple attack, resulting in a denial of service that affects system availability. No data theft or system compromise occurs, but productivity is lost due to service unavailability.
