Published: 28 January 2026
Summary
CVE-2025-65891 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 7.4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Threat & Defense at a Glance
Threat & Defense Details
Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Limiting concurrent sessions directly prevents uncontrolled resource consumption by capping the number of active sessions per user or account.
Analysis identifies uncontrolled resource consumption indicative of denial-of-service or abuse attempts.
Contingency plan testing includes resource exhaustion scenarios to verify recovery, making it harder for attackers to sustain exploits that cause uncontrolled consumption.
Updated contingency plans include current procedures to detect, contain, and recover from resource exhaustion, limiting an attacker's ability to sustain impact from uncontrolled consumption.
Alternate site allows resumption of operations if resource exhaustion at the primary site is exploited to cause unavailability.
Alternate telecommunications services enable resumption of essential functions when primary services become unavailable due to uncontrolled resource consumption.
The team can analyze and respond to resource exhaustion incidents, reducing the impact of attacks that exploit uncontrolled consumption weaknesses.
Timely maintenance support and spare parts enable rapid recovery from failures induced by uncontrolled resource consumption, shortening the impact window of denial-of-service attacks.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Vulnerability directly enables remote exploitation of the application to trigger crash/resource exhaustion (DoS) via invalid input to exposed function.
NVD Description
A GPU device-ID validation flaw in OneFlow v0.9.0 allows attackers to trigger a Denial of Dervice (DoS) by invoking flow.cuda.get_device_properties() with an invalid or negative device index.
Deeper analysisAI
CVE-2025-65891 is a GPU device-ID validation flaw present in OneFlow version 0.9.0. The vulnerability resides in the flow.cuda.get_device_properties() function, which does not properly validate device indices, permitting invalid or negative values to be processed and leading to a crash.
The vulnerability has 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 it is exploitable over the network with low attack complexity, no privileges or user interaction required, and results in high availability impact through denial of service (DoS). Remote attackers can invoke the affected function with an invalid or negative device index to trigger resource exhaustion or process termination on systems running the vulnerable OneFlow instance, as classified under CWE-400 (Uncontrolled Resource Consumption).
Mitigation details and related discussions are available in the vendor references, including the OneFlow website at http://oneflow.com, the project repository at https://github.com/Oneflow-Inc/oneflow, and the specific issue tracker at https://github.com/Oneflow-Inc/oneflow/issues/10661. Security practitioners should review these for patches or workarounds in OneFlow v0.9.0 and later versions.
