CVE-2025-59289

Local privilege escalation via double free

Published Oct 14, 2025 · Updated Oct 14, 2025

A double free in Microsoft Windows Bluetooth Service allows local users with existing access to elevate privileges on affected Windows systems. The service releases the same memory allocation twice during an undisclosed operation; Microsoft has not identified the object or code path involved. Exploitation requires low privileges and a high-complexity local sequence, and successful execution grants elevated control over the affected system.
