Q: Given the following code slice:
```
CWE-476___CVE-2024-36011.c___1-70___63.c_vul.c
1 static void hci_le_big_sync_established_evt(struct hci_dev *hdev, void *data,
2 					    struct sk_buff *skb)
4 	struct hci_evt_le_big_sync_estabilished *ev = data;
5 	struct hci_conn *bis;
7 	int i;
11 	if (!hci_le_ev_skb_pull(hdev, skb, HCI_EVT_LE_BIG_SYNC_ESTABILISHED,
26 	for (i = 0; i < ev->num_bis; i++) {
27 		u16 handle = le16_to_cpu(ev->bis[i]);
30 		bis = hci_conn_hash_lookup_handle(hdev, handle);
31 		if (!bis) {
32 			bis = hci_conn_add(hdev, ISO_LINK, BDADDR_ANY,
34 			if (!bis)
59 	if (ev->status)
60 		for (i = 0; i < ev->num_bis; i++) {
61 			u16 handle = le16_to_cpu(ev->bis[i]);
63 			bis = hci_conn_hash_lookup_handle(hdev, handle);

```
which has a vulnerability among CWE-476 and among lines:
```
63 			bis = hci_conn_hash_lookup_handle(hdev, handle);
```
Please generate five possible patches for the vulnerability.
