finds

Security testing in development catches missing or incorrect return-value checks.

prevents

Secure SDLC mandates return-value checks and error handling, directly reducing CWE-253.

prevents

Application security requirements include robust error handling that mitigates incorrect return-value checks.

prevents

Secure architecture principles require defensive coding practices such as validating function results.

prevents

Secure coding explicitly demands checking return values, covering most of CWE-253.
