Description
A use-after-free vulnerability in the Linux kernel Bluetooth coredump functionality was resolved. The issue occurs because dump work queues remain live after device unregister, allowing access to freed device references during disconnect. The fix involves shutting down coredump processing during unregister and properly synchronizing access to prevent use-after-free.
