# Intel Wireless Bluetooth driver: out-of-bounds write can crash the kernel

Link for people: https://infrastack.ai/live/CVE-2026-42956 (this .md is for agents)

An out-of-bounds memory write in some Intel Wireless Bluetooth drivers, running in kernel mode, can be triggered from nearby over the adjacent network. The result is a denial of service that can take the machine down, with no confidentiality or integrity impact stated.

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

## Affected

- vendor:Intel Wireless Bluetooth affected < 24.50 fixed 24.50

## How to check

On Windows, open Device Manager > Bluetooth > Intel(R) Wireless Bluetooth(R) > Properties > Driver and read the driver version. Versions before 24.50 are affected. No Intel Wireless Bluetooth adapter means not affected.

## Fix

Update Intel Wireless Bluetooth for Windows to version 24.50 or later (Intel download: https://www.intel.com/content/www/us/en/download/18649/intel-wireless-bluetooth-for-windows-10-and-windows-11.html)

## From the sources

Out-of-bounds write for some Intel(R) Wireless Bluetooth(R) within Ring 0: Kernel 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 (none) impacts.
