Local privilege escalation via Bluetooth service race
Published Sep 8, 2026 · Updated Sep 9, 2026
A race condition in Microsoft Windows Bluetooth Service allows local users with code-execution access to elevate privileges on affected systems. The service permits concurrent access to an undisclosed shared resource without proper synchronization, creating the privilege-escalation race. Exploitation requires prior authorization and local code execution; Microsoft has not disclosed the raced resource or resulting privilege level.
