Weakness (CWE)

CWE-194: Unexpected Sign Extension

Variant Incomplete

The product performs an operation on a number that causes it to be sign extended when it is transformed into a larger data type.

How to prevent it (1 mitigation)

  1. Implementation

    Avoid using signed variables if you don't need to represent negative values. When negative values are needed, perform validation after you save those values to larger data types, or before passing them to functions that are expecting unsigned values.
