CVE-2026-31771: In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_event: move wake reason storage into

Move hci_store_wake_reason() calls from the general event handler into nine specific event handlers (hci_conn_request_evt, hci_conn_complete_evt, hci_sync_conn_complete_evt, le_conn_complete_evt, hci_le_adv_report_evt, hci_le_ext_adv_report_evt, hci_le_direct_adv_report_evt, hci_le_pa_sync_established_evt, and hci_le_past_received_evt) where event-length validation has already succeeded. Convert hci_store_wake_reason() into a helper that only stores validated addresses while holding hci_dev_lock(), and annotate it with __must_hold(&hdev->lock) and lockdep_assert_held(&hdev->lock) to enforce the lock requirement.
