Weaknesses
CWE · root cause- CWE-414Missing Lock CheckA product does not check to see if a lock is present before performing sensitive operations on a resource.
- CWE-416Use After FreeThe 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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
