Summary

CVE-2025-5899 is a low-severity Free of Memory not on the Heap (CWE-590) vulnerability in Gnu (inferred from references). Its CVSS base score is 1.9 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 4th 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 (static/dynamic analysis) can discover incorrect free() calls on non-heap memory.

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

Documented development standards and tools can require correct heap allocation/deallocation discipline, stopping the defect at introduction.

Mitigating Controls (NIST CSF 2.0) AI

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 directly prevent incorrect free() calls via code review, static analysis, and developer training.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

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

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

Security testing in development can detect invalid-free defects before release.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle mandates memory-safety practices that reduce use-after-free and invalid-free bugs.

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

Secure architecture and engineering principles include disciplined memory management that prevents freeing non-heap memory.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly forbid freeing pointers not obtained from heap allocators, directly mitigating CWE-590.
