Windows PCs with an Intel Wireless Bluetooth adapter and a driver older than 24.50 are exposed. Intel lists integrated wireless on 10th to 14th generation Core, Core Ultra Series 1 and 2, and related Pentium and Celeron processors, plus discrete AC 9260 to Wi-Fi 7 BE201 adapters. An attacker within Bluetooth range needs no login or user action and can crash the machine (denial of service). Machines without an Intel Bluetooth adapter can skip it.

Who cares adjacent-network, bluetooth, intel, laptops, windows
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.
