Out-of-Bounds Write in Intel PROSet/Wireless WiFi Software

Publication date: 2026-08-11

Last updated on: 2026-08-11

Assigner: Intel Corporation

Description
Out-of-bounds write 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 passive 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.

Executive Summary

This is an out-of-bounds write vulnerability in Intel PROSet/Wireless WiFi Software for Windows. It may allow a network-based attacker to cause a denial of service via adjacent access without special internal knowledge. The attack requires passive user interaction and has low complexity.

Impact Analysis

The vulnerability could lead to system crashes or instability, resulting in reduced availability of the affected device. Since it requires adjacent network access and passive user interaction, exploitation is limited but still poses a risk to system uptime.

Compliance Impact

This vulnerability primarily impacts system availability, which could affect compliance with regulations requiring high availability of systems handling sensitive data. However, since confidentiality and integrity impacts are none, direct compliance risks may be limited unless availability is a critical requirement.

Mitigation Strategies

Update Intel PROSet/Wireless WiFi Software for Windows to the latest version provided by Intel to patch the out-of-bounds write vulnerability.
