CVE-2026-20731 is a medium-severity flaw (CVSS 6.1) affecting neural processing unit driver, neural processing unit driver. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
Improper buffer restrictions for the Intel(R) NPU Driver for all versions within Ring 3: User Applications 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 vulnerabil
