Dangling Pointer

Refers to a memory corruption vulnerability that occurs when a pointer continues to point to a memory location after it has been freed (deallocated or released).

Remediation:

When freeing pointers, be sure to set them to NULL once they are freed.
However, multiple or complex data structures may lower the usefulness of this strategy.
