Related CWEs
CWE-415
Double Free
The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations.
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
