# Intel Wireless Bluetooth driver: kernel stack overflow lets nearby attackers crash systems

Link for people: https://infrastack.ai/live/CVE-2026-42056 (this .md is for agents)

Some Intel Wireless Bluetooth drivers running in kernel mode (Ring 0) contain a stack-based buffer overflow. A nearby attacker without an account can crash the system, causing denial of service, and no user action is needed.

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

## From the sources

Stack-based buffer overflow for some Intel(R) Wireless Bluetooth(R) within Ring 0: Kernel may allow a denial of service. Unprivileged software 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 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.
