CVE-2023-53762 is a use-after-free vulnerability in the Linux kernel Bluetooth subsystem's hci_disconnect_all_sync connection-cleanup logic. Concurrent controller-event processing can delete a Bluetooth connection object while hci_disconnect_all_sync is iterating the connection list, leaving the synchronization path with a stale reference. The condition can manifest as a slab use-after-free during Bluetooth power-state handling. The upstream correction iterates the list in reverse order to clean child links before parent objects and removes cursor-based iteration, instead processing the last element because hci_abort_conn_sync deletes the connection.
