  "description": "In the Linux kernel, the following vulnerability has been resolved:  Bluetooth: hci_event: Fix OOB read and infinite loop in hci_le_create_big_complete_evt  hci_le_create_big_complete_evt() iterates over BT_BOUND connections for a BIG handle using a while loop, accessing ev-\u003Ebis_handle[i\u002B\u002B] on each iteration.  However, there is no check that i stays within ev-\u003Enum_bis before the array access.  When a controller sends a LE_Create_BIG_Complete event with fewer bis_handle entries than there are BT_BOUND connections for that BIG, or with num_bis=0, the loop reads beyond the valid bis_handle[] flex array into adjacent heap memory.  Since the out-of-bounds values typically exceed HCI_CONN_HANDLE_MAX (0x0EFF), hci_conn_set_handle() rejects them and the connection remains in BT_BOUND state.  The same connection is then found again by hci_conn_hash_lookup_big_state(), creating an infinite loop with hci_dev_lock held.  Fix this by terminating the BIG if in case not all BIS could be setup properly.",
