blocks

Secure SDLC mandates input validation and bounds checking that can prevent out-of-range pointer offsets.

A.8.26 Application security requirements partial match
blocks

A.8.26 only requires that security requirements (including resilience against buffer overflows or SQL injections) be identified and specified during development or acquisition; it does not itself enforce, implement, or prevent out-of-range pointer arithmetic in the resulting application.

A.8.27 Secure system architecture and engineering principles partial match

Secure coding standards directly forbid unsafe pointer arithmetic and require bounds checks.

Security testing can detect out-of-range pointer offsets before release.
