Lin Ma 74caf718cc Bluetooth: use correct lock to prevent UAF of hdev object ... commit e305509e678b3a4af2b3cfd410f409f7cdaabb52 upstream. The hci_sock_dev_event() function will cleanup the hdev object for sockets even if this object may still be in used within the hci_sock_bound_ioctl() function, result in UAF vulnerability. This patch replace the BH context lock to serialize these affairs and prevent the race condition.
