Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires validation of input (including device-supplied data) to enforce bounds checking and reject malformed HID payloads before they reach vulnerable parsing code.

prevent

Restricts or authorizes access to I/O ports and devices, enabling blocking or filtering of untrusted/malicious HID devices at the hardware-interface layer.

prevent

Provides memory-protection mechanisms that can contain or prevent crashes resulting from out-of-bounds accesses triggered by the malicious HID input.

detects

Security testing in development catches out-of-bounds accesses before release, covering most instances of the weakness.

prevents

Secure development lifecycle mandates memory-safety practices that directly prevent buffer-boundary violations.

prevents

Application security requirements can specify memory-safety rules, but do not prescribe implementation details.

prevents

Secure architecture and engineering principles include memory-safe design patterns that mitigate buffer overflows.

prevents

Secure coding standards explicitly forbid unsafe buffer operations, directly eliminating CWE-119.
