# Intel Wireless Bluetooth driver: use-after-free lets a local user crash the kernel

Link for people: https://infrastack.ai/live/CVE-2026-44625 (this .md is for agents)

A use-after-free bug in Intel Wireless Bluetooth driver code running in kernel mode can be triggered by a logged-in local user. The result is a denial of service that can take the machine down, with no confidentiality or integrity loss stated.

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

## How to check

- Check whether the machine has an Intel Wireless Bluetooth adapter and driver installed (Device Manager on Windows, or `lsmod` / `dmesg` on Linux)
- Compare the installed driver version against the fixed version in Intel's advisory: unknown

## Timeline

## From the sources

Use after free for some Intel(R) Wireless Bluetooth(R) within Ring 0: Kernel may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable denial of service. 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 (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
