Summary:
Potential security vulnerabilities for some Intel® PROSet/Wireless WiFi Software may allow escalation of privileges or denial of service. Intel is releasing software updates to mitigate these potential vulnerabilities.
Vulnerability Details:
CVEID: CVE-2026-20789
Description: Improper access control for some Intel® PROSet/Wireless WiFi Software for Windows within Ring 2: Device Drivers may allow an escalation of privilege. Unprivileged software adversary with an unauthenticated user combined with a low complexity attack may enable local code execution. 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 (high), integrity (low) and availability (low) impacts.
CVSS Base Score: 8.4 High
