Official description

NULL pointer dereference in some Intel(R) PROSet/Wireless WiFi and Killerâ„¢ WiFi software for Windows before version 23.80 may allow an unauthenticated user to potentially enable denial of service via adjacent access.

The underlying weakness: NULL Pointer Dereference

The product dereferences a pointer that it expects to be valid but is NULL.

How developers prevent this class of flaw

  • 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.
  • Select a programming language that is not susceptible to these issues.
  • Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
