In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_event: fix potential UAF in hci_le_remote_conn_param_req_evt
hci_conn lookup and field access must be covered by hdev lock in hci_le_remote_conn_param_req_evt, otherwise it's possible it is freed concurrently.
Extend the hci_dev_lock critical section to cover all conn usage.
