Summary

CVE-2025-71000 is a high-severity Uncontrolled Resource Consumption (CWE-400) vulnerability in Oneflow Oneflow. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 36.8th 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 are NIST 800-53 SC-5 (Denial-of-service Protection) and SI-10 (Information Input Validation).

Deeper analysis

CVE-2025-71000 is a vulnerability in the flow.cuda.BoolTensor component of OneFlow version 0.9.0. The issue enables attackers to trigger a Denial of Service (DoS) condition by providing a crafted input. It carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), indicating high severity primarily due to its impact on availability, and is linked to CWE-400 (Uncontrolled Resource Consumption). The vulnerability was published on 2026-01-28.

Attackers can exploit this remotely over a network with low complexity, without requiring authentication, privileges, or user interaction. Successful exploitation results in high availability disruption, such as crashing the affected OneFlow process or causing significant resource exhaustion, while confidentiality and integrity remain unaffected.

Mitigation details and related advisories can be found in the provided references: the OneFlow website at http://oneflow.com, https://github.com/Daisy2ang, and the specific issue tracker at https://github.com/Oneflow-Inc/oneflow/issues/10659. Security practitioners using OneFlow in AI/ML workflows with CUDA tensors should consult these for patches or workarounds.
