"value": "AV:L - The vulnerability is reached by writing MGMT commands to a local AF_BLUETOOTH/BTPROTO_HCI socket bound to HCI_CHANNEL_CONTROL (hci_sock_sendmsg → hci_mgmt_cmd), plus the HCIDEVDOWN ioctl path; no over-the-air Bluetooth traffic is involved.\nAC:L - The attacker drives both halves from the same socket — issue SET_POWERED(off), whose hci_dev_close_sync does workqueue drains and controller shutdown commands, then queue a second cmd_sync entry into that window — and can retry the sequence indefinitely until it lands.\nPR:L - Sending these MGMT opcodes requires the HCI_SOCK_TRUSTED flag (CAP_NET_ADMIN), which on real deployments is held by the Bluetooth daemon/stack process (bluetoothd, Android AID_BLUETOOTH) rather than full root, so a compromised low-privileged Bluetooth service reaches this directly.\nUI:N - The entire sequence is driven by the attacker's own MGMT socket writes; no victim action or interaction is needed.\nS:U - The deadlock and memory corruption are confined to the kernel's own security authority — there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - Callbacks such as start_discovery_complete and read_local_oob_ext_data_complete free the mgmt_pending_cmd, after which cmd_complete_rsp reads cmd->cmd_complete from the freed GFP_KERNEL slab object; a heap-sprayed reclaim of that object yields a controlled read primitive and disclosure of kernel memory.\nI:H - The stale cmd is dereferenced for an indirect function-pointer call (cmd->cmd_complete(cmd, status)) and then passed to mgmt_pending_remove a second time, giving a double free plus list_del on freed memory — a control-flow-hijack and arbitrary-write primitive.\nA:H - mgmt_set_connectable_complete/mgmt_set_discoverable_complete re-acquire hdev->lock already held by hci_dev_close_sync, permanently deadlocking the hci_cmd_sync_work kworker while holding that mutex, and the UAF/double-free path independently corrupts the slab and panics the kernel."
