CVE-2023-24947

Unauthenticated code execution via Bluetooth use-after-free

Published May 9, 2023 · Updated Jul 10, 2025

Use-after-free in the Windows Bluetooth Driver in affected Windows 10 and Server releases allows physically proximate attackers to execute code. Microsoft identifies CWE-416 but has not disclosed the affected object, function, or precise lifetime error in the driver. Exploitation requires Bluetooth proximity but no authentication or user interaction, and successful code execution can fully compromise the host.
