Denial of Service in Intel PROSet/Wireless WiFi Software

Publication date: 2026-08-11

Last updated on: 2026-08-26

Assigner: Intel Corporation

Description

Improper conditions check for some Intel(R) PROSet/Wireless WiFi Software 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 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 (none) and availability (high) impacts.

Attack-Flow Graph

Executive Summary

This is a denial of service vulnerability in Intel PROSet/Wireless WiFi Software. It allows an unauthenticated network attacker to cause a system outage via adjacent access without special knowledge or user interaction. The attack has low complexity and exploits improper conditions checks in Ring 2 device drivers.

Detection Guidance

This vulnerability involves Intel PROSet/Wireless WiFi Software and may allow denial of service via adjacent network access. Detection requires checking installed versions of the software and monitoring for unusual network activity or crashes. No specific commands are provided in the context.

Impact Analysis

The vulnerability can cause system unavailability, leading to service disruptions. It does not affect confidentiality or integrity but may result in high availability impact for the vulnerable system and subsequent systems.

Compliance Impact

This vulnerability primarily impacts system availability with high severity, which could lead to service disruptions. For GDPR, availability issues may affect data processing operations but do not directly violate confidentiality or integrity requirements. HIPAA compliance could be impacted if the DoS affects systems handling protected health information, potentially disrupting access to critical data.

Mitigation Strategies

Apply updates or patches from Intel for the PROSet/Wireless WiFi Software. Disable the vulnerable component if updates are unavailable. Monitor network traffic for signs of exploitation and restrict adjacent network access to reduce attack surface.
