  "details": "In the Linux kernel, the following vulnerability has been resolved:  Bluetooth: hci_sync: annotate data-races around hdev-\u003ereq_status  __hci_cmd_sync_sk() sets hdev-\u003ereq_status under hdev-\u003ereq_lock:      hdev-\u003ereq_status = HCI_REQ_PEND;  However, several other functions read or write hdev-\u003ereq_status without holding any lock:    - hci_send_cmd_sync() reads req_status in hci_cmd_work (workqueue)   - hci_cmd_sync_complete() reads/writes from HCI event completion   - hci_cmd_sync_cancel() / hci_cmd_sync_cancel_sync() read/write   - hci_abort_conn() reads in connection abort path  Since __hci_cmd_sync_sk() runs on hdev-\u003ereq_workqueue while hci_send_cmd_sync() runs on hdev-\u003eworkqueue, these are different workqueues that can execute concurrently on different CPUs. The plain C accesses constitute a data race.  Add READ_ONCE()/WRITE_ONCE() annotations on all concurrent accesses to hdev-\u003ereq_status to prevent potential compiler optimizations that could affect correctness (e.g., load fusing in the wait_event condition or store reordering).",
