Summary

CVE-2025-71002 is a medium-severity Divide By Zero (CWE-369) vulnerability in Oneflow Oneflow. Its CVSS base score is 6.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Endpoint Denial of Service (T1499); ranked at the 20th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

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 (including static/dynamic analysis) finds divide-by-zero conditions after they have been coded.

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

Requiring documented development standards and tools can mandate safe typing, casting rules, and compiler checks that stop the weakness from being introduced.

SA-8 Security and Privacy Engineering Principles partial match

Security engineering principles can require safe-arithmetic constructs or explicit guards that keep division operands nonzero.

SI-10 Information Input Validation partial match

Validating numeric inputs before use as divisors structurally blocks zero values from reaching division operations.
