Summary

CVE-2024-25388 is a high-severity Signed to Unsigned Conversion Error (CWE-195) vulnerability in Rt-Thread Rt-Thread. Its CVSS base score is 8.4 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 25th 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

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover conversion errors through static analysis, fuzzing, or targeted unit tests.

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

Requiring documented development standards and tools can enforce coding rules that prohibit or safely wrap such casts.

SA-8 Security and Privacy Engineering Principles partial match

Engineering principles can mandate safe integer handling and strong typing to avoid unsafe signed-to-unsigned casts.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices (static analysis, code review, safe-integer standards) directly prevent signed-to-unsigned conversion errors.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development can detect conversion-related defects before release.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates practices that can catch signed-to-unsigned conversion errors during design and coding.

A.8.26 Application security requirements partial match
prevents

Application security requirements can specify safe integer handling and type-conversion rules.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure system architecture and engineering principles include data-type safety and overflow prevention.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly prohibit unsafe signed-to-unsigned casts and require defensive checks.
