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?
Directly enables Endpoint DoS via application exploitation (crafted tensor input triggers resource exhaustion in exposed OneFlow service).
NVD Description
A shape mismatch vulnerability in OneFlow v0.9.0 allows attackers to cause a Denial of Service (DoS) via supplying crafted tensor shapes.
Deeper analysisAI
CVE-2025-65886 is a shape mismatch vulnerability affecting OneFlow version 0.9.0, an open-source framework handling tensor operations. The flaw enables attackers to trigger a Denial of Service (DoS) condition by supplying crafted tensor shapes, as documented under CWE-400 (Uncontrolled Resource Consumption). Published on 2026-01-28 with 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), it poses a high-impact availability risk without compromising confidentiality or integrity.
The vulnerability is exploitable by unauthenticated attackers over the network with low attack complexity and no user interaction required. By delivering specially crafted tensor shapes to a vulnerable OneFlow instance, attackers can cause resource exhaustion or crashes, leading to service disruption. This scenario targets deployments exposing OneFlow endpoints, such as in distributed training or inference setups.
Mitigation details and patches are referenced in the OneFlow GitHub repository (https://github.com/Oneflow-Inc/oneflow), specific issue tracker (https://github.com/Oneflow-Inc/oneflow/issues/10666), and related sites including http://oneflow.com and https://github.com/Daisy2ang. Security practitioners should review these for upgrade guidance or workarounds to address the issue in v0.9.0.
As a tensor shape issue in an AI/ML framework, CVE-2025-65886 highlights risks in deep learning pipelines where malformed inputs can propagate to DoS, though no real-world exploitation has been reported in the provided data.
