Value is never used after assignment
The VA_UNUSED.GEN checker finds values assigned to local variables that are never used before the next assignment or the end of the function.
Vulnerability and risk
Unused variable values can indicate that
- an incorrect variable may be used later in the code
- there are significant logic errors or other problems with the code
Vulnerable code example
i = f();
i = g();
Klocwork flags line 3, indicating that 'i' is initialized with value returned from function f(), but the value is never used.
