CVE-2026-20741

Severity CVSS v4.0:
HIGH
Type:
CWE-284 Improper Access Control
Publication date:
11/08/2026
Last modified:

Description

Improper access control for some Intel(R) PROSet/Wireless WiFi Software within Ring 2: Device Drivers may allow a denial of service. Unprivileged software adversary with an unauthenticated 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 vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (low) and availability (high) impacts.
