Detailsinfo

A vulnerability, which was classified as critical, was found in Intel PROSet and Wireless WiFi Software (the affected version unknown). This affects an unknown part of the component Device Drivers. The manipulation with an unknown input leads to a denial of service vulnerability. CWE is classifying the issue as CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. This is going to have an impact on availability. The summary by CVE is:

Improper conditions check for some Intel(R) PROSet/Wireless WiFi Software for Windows within Ring 2: Device Drivers may allow a denial of service. Network adversary with an unauthenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via adjacent 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 (low) impacts.

The advisory is shared at intel.com. This vulnerability is uniquely identified as CVE-2026-20739 since 12/03/2025. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available.
