CWE-1341 Multiple Releases of Same Resource or Handle

The product attempts to close or release a resource or handle more than once, without any successful open between the close operations.

CWE-415 Double Free

The product calls free() twice on the same memory address.

CWE-416 Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
