Mitigation MIT-53
Check the results of all functions that return a value and verify that the value is expected.
Mitigation MIT-56
For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation
Ensure that you account for all possible return values from the function.
Mitigation
When designing a function, make sure you return a value or throw an exception in case of an error.
No CAPEC attack patterns related to this CWE.
