Published: 28 January 2026
Summary
CVE-2025-70999 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 14.8th 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-2025-70999 is a GPU device-ID validation flaw in the flow.cuda.get_device_capability() component of OneFlow v0.9.0. This vulnerability enables attackers to trigger a Denial of Service (DoS) condition by supplying a crafted device ID. 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 due to its potential for significant availability impact, and is linked to CWE-400 (Uncontrolled Resource Consumption). The CVE was published on 2026-01-28.
Remote attackers require no privileges or user interaction to exploit this flaw over the network with low complexity. Successful exploitation results in a DoS, disrupting the availability of the affected OneFlow instance without impacting confidentiality or integrity.
Mitigation guidance and patches are referenced in vendor resources, including the OneFlow website at http://oneflow.com, https://github.com/Daisy2ang, and the issue tracker at https://github.com/Oneflow-Inc/oneflow/issues/10660. Security practitioners should consult these for updates and remediation steps specific to OneFlow v0.9.0.
