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 buffer restrictions for some Intel(R) PROSet/Wireless WiFi Software for Windows 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 (low) impacts.

CWE

KEV

CWE ID	Description
CWE-119	The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.

Attack-Flow Graph

Executive Summary

This is a denial of service vulnerability in Intel PROSet/Wireless WiFi Software for Windows. It allows an unauthenticated network attacker to cause a system crash via adjacent access without special knowledge or user interaction. The attack has low complexity and impacts system availability.

Detection Guidance

This vulnerability may not have direct detection commands due to its nature as a potential denial of service issue in Intel PROSet/Wireless WiFi Software. Monitor for unusual network activity or system crashes related to wireless drivers. Check Intel's official advisories for updates or patches.

Impact Analysis

The vulnerability can cause your system to become unresponsive or crash, leading to loss of network connectivity and potential downtime. It does not directly expose data but disrupts normal operations.
