CVE-2025-65890
Published: 28 January 2026
Summary
CVE-2025-65890 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 Exploit Public-Facing Application (T1190); ranked at the 16.9th 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-2025-65890 is a device-ID validation flaw present in OneFlow version 0.9.0. This vulnerability affects the flow.cuda.synchronize() function, where attackers can supply an invalid or out-of-range GPU device index, leading to a Denial of Service (DoS) condition. The issue is classified under CWE-400 (Uncontrolled Resource Consumption) and 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), highlighting its potential for high availability impact without compromising confidentiality or integrity.
Remote attackers can exploit this vulnerability over the network with low attack complexity, requiring no privileges, authentication, or user interaction. By invoking flow.cuda.synchronize() with a malformed GPU device index, adversaries can disrupt affected OneFlow processes, potentially causing resource exhaustion or crashes on systems utilizing CUDA for GPU acceleration.
For mitigation guidance and patches, security practitioners should consult the vendor references, including the OneFlow website at http://oneflow.com, the project repository at https://github.com/Oneflow-Inc/oneflow, and the dedicated issue tracker at https://github.com/Oneflow-Inc/oneflow/issues/10662.
