Detailsinfo

A vulnerability, which was classified as problematic, was found in Intel NPU Driver on Windows. Affected is an unknown code block. The manipulation with an unknown input leads to a sensitive information in resource not removed before reuse vulnerability. CWE is classifying the issue as CWE-226. The product releases a resource such as memory or a file so that it can be made available for reuse, but it does not clear or "zeroize" the information contained in the resource before the product performs a critical state transition or makes the resource available for reuse by other entities. This is going to have an impact on confidentiality. CVE summarizes:

Sensitive information uncleared in resource before release for reuse for some Intel(R) NPU Drivers for Windows before version 32.0.100.4023 within Ring 3: User Applications may allow an information disclosure. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable data exposure. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (low), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

The advisory is shared for download at intel.com. This vulnerability is traded as CVE-2025-20622 since 01/07/2025. The exploitability is told to be easy. The attack needs to be approached locally. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1592.

Upgrading to version 32.0.100.4023 eliminates this vulnerability.
