CVE-2025-43965
Imagemagick ≤ 7.1.1-44
Raw vector
CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:LCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2025-43965 is a low-severity Incorrect Calculation of Buffer Size (CWE-131) vulnerability in Imagemagick Imagemagick. Its CVSS base score is 2.9 (Low).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 44th 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-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Developer security testing and code review can discover incorrect buffer-size computations before deployment.
Secure engineering principles directly require correct buffer-size arithmetic and bounds-checked allocation.
Input validation can enforce that supplied lengths or counts used in size calculations are within safe bounds.
Memory-protection mechanisms limit the exploitability of an overflow that results from an incorrect size calculation.
Flaw-remediation processes that include vulnerability scanning or static analysis will surface buffer-size errors.

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.
Secure SDLC practices directly prevent buffer-size miscalculations via coding standards, reviews, and testing, while fixing this single weakness only partially fulfills the broader control.
