Weakness (CWE)
CWE-476: NULL Pointer Dereference
The product dereferences a pointer that it expects to be valid but is NULL.
How to prevent it (5 mitigations)
-
Implementation
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].
-
Requirements
Select a programming language that is not susceptible to these issues.
-
Implementation
Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
-
Architecture and Design
Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
-
Implementation
Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
