Deletion of arbitrary node in the linked list

Given any node in a liked list without start pointer, how will you delete that node?
And what problem(s) will arise?

Solution is swap content of it with the next node (pointed by next pointer). And delete next node instead.
Problem will arise when this will be a terminal node (node with null next pointer). It will free a memory location that is longer used and still pointed by a node of linked list.
