Privilege escalation in Intel Proset\/wireless Wifi
CVE-2026-20890
Improper privilege management for some Intel(R) PROSet/Wireless WiFi Software for Windows within Ring 2: Privileged Process may allow an escalation of privilege. Unprivileged software adversary with an unauthenticated user combined with a high complexity attack may enable escalation of privilege. 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 (low), integrity (low) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (low), integrity (low) and availability (high) impacts.
