Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); 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 allows remote unauthenticated exploitation of a public-facing ML framework service (T1190) to trigger application/system DoS via invalid input leading to resource exhaustion or crash (T1499.004).
NVD Description
A device-ID validation flaw in OneFlow v0.9.0 allows attackers to cause a Denial of Service (DoS) by calling flow.cuda.synchronize() with an invalid or out-of-range GPU device index.
Deeper analysisAI
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.
