Status: Draft Weakness ID: 563 (Weakness Variant)Description Summary The variable's value is assigned but never used, making it a dead store. Extended Description It is likely that the variable is simply vestigial, but it is also possible that the unused variable points out a bug. Potential Mitigations Remove unused variables from the code. Demonstrative Examples The following code excerpt assigns to the variable r and then overwrites the value without using it. r = getName(); r = getNewBuffer(buf);
Other Notes This variable's value is not used. After the assignment, the variable is either assigned another value or goes out of scope. Relationships
