# Intel Wireless Software for Windows: use-after-free lets local users crash system

Link for people: https://infrastack.ai/live/CVE-2026-40697 (this .md is for agents)

Some Intel Wireless Software for Windows versions have a use-after-free bug in code that runs in user mode (Ring 3). A logged-in local user with an ordinary account can trigger it to cause a denial of service.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Intel wireless software version in Windows Settings > Apps, or with the Intel driver package information

## From the sources

Use after free for some Intel(R) Wireless Software for Windows within Ring 3: User Applications may allow denial of service. Unprivileged software adversary with an authenticated user combined with a high complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (low) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (low) and availability (low) impacts.
