"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: coredump: Quiesce dump work on unregister\n\nhci_devcd_handle_pkt_init() arms dump_timeout and coredump producers\nqueue dump_rx without holding an hdev reference. Unregister leaves both\nworks live, so disconnecting during an active dump lets them access hdev\nafter hci_release_dev() frees it.\n\nShut down coredump processing during unregister. Close the producer gate\nunder dump_q.lock before disabling both works, then free the active buffer\nand queued packets under hci_dev_lock. Serializing the gate with enqueue\nprevents controller-specific workers from adding packets after the final\npurge."
