In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: 6lowpan: check skb_clone() return value in send_mcast_pkt()
The skb_clone() function can return NULL if memory allocation fails. send_mcast_pkt() calls skb_clone() without checking the return value, which can lead to a NULL pointer dereference in send_pkt() when it dereferences skb->data. Add a NULL check after skb_clone() and skip the peer if the clone fails.
