# Intel Wireless Bluetooth driver: kernel null pointer lets local user crash system

Link for people: https://infrastack.ai/live/CVE-2026-40695 (this .md is for agents)

A null pointer dereference in Intel Wireless Bluetooth driver code running in the kernel (Ring 0) lets a local user who is logged in cause a denial of service. The sources describe only an availability impact; no confidentiality or integrity loss is stated.

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

## From the sources

Null pointer dereference 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.
