CVE-2026-20886

Out-of-Bounds Write Allowing Denial of Service in Intel PROSet/Wireless WiFi Drivers on Windows

Published Aug 11, 2026 CVSS 4.0 · 6.9 Medium EPSS < 1% KEV · Not listed

Description

Out-of-bounds write 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 passive 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.
