Weakness (CWE)
CWE-415: Double Free
The product calls free() twice on the same memory address.
How to prevent it (3 mitigations)
-
Architecture and Design
Choose a language that provides automatic memory management.
-
Implementation
Ensure that each allocation is freed only once. After freeing a chunk, set the pointer to NULL to ensure the pointer cannot be freed again. In complicated error conditions, be sure that clean-up routines respect the state of allocation properly. If the language is object oriented, ensure that object destructors delete each chunk of memory only once.
-
Implementation
Use a static analysis tool to find double free instances.
