Summary

CVE-2024-21470 is a high-severity Integer Overflow to Buffer Overflow (CWE-680) vulnerability in Qualcomm Aqt1000 Firmware. Its CVSS base score is 8.4 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked at the 1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and analysis (static, dynamic, fuzzing) finds integer-overflow-to-allocation defects before deployment.

SA-15 Development Process, Standards, and Tools partial match

Mandates documented development standards and tools that enforce secure coding rules against unsafe integer arithmetic.

SA-8 Security and Privacy Engineering Principles partial match

Requires engineering principles such as safe arithmetic and bounds-checked allocation that directly stop integer overflow during memory-size computation.

SI-10 Information Input Validation partial match

Validates untrusted size/offset inputs before they reach allocation calculations, structurally blocking the integer overflow path.

Secure SDLC practices directly prevent integer-overflow flaws during development, but eliminating only this CWE covers only part of the broad control intent.
