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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/24af375d7d8aa5f698e4dc41317102f44114351a","tags":[]},{"url":"https://git.kernel.org/stable/c/82699d1b727ba5980b94f1eb8dc3d346f41b7c67","tags":[]},{"url":"https://git.kernel.org/stable/c/d236517c264e41dc09833c708ef23bccb7a91219","tags":[]},{"url":"https://git.kernel.org/stable/c/dcaf10ef27f928568c25de3e9fc242e538de5c67","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
