Improper Access Control in Intel PROSet/Wireless WiFi Software

Publication date: 2026-08-11

Last updated on: 2026-08-11

Assigner: Intel Corporation

Description
Improper access control for some Intel(R) 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.
