Summary

CVE-2025-65886 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 OS Exhaustion Flood (T1499.001); ranked at the 30th 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 map to SC-5 (Denial-of-service Protection) and SC-6 (Resource Availability) — see the control section below for these in your framework.

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.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SC-5 directly limits the effects of resource-exhaustion events that constitute uncontrolled consumption.

SC-6 enforces explicit allocation limits on resources, structurally preventing the weakness from occurring.

Process isolation confines resource consumption to separate domains, reducing blast radius without stopping the root flaw.

PR.IR-04 mostly match
prevents

Explicitly requires monitoring and maintaining resource capacity, directly addressing uncontrolled consumption to preserve availability.

DE.CM-09 partial match
prevents

Continuous monitoring of computing resources can detect resource exhaustion but does not itself enforce allocation limits.

PR.IR-03 partial match
prevents

Resilience mechanisms such as avoiding single points of failure indirectly reduce impact of resource exhaustion.

PR.PS-01 partial match
prevents

Hardened configuration baselines can include resource quotas and limits that constrain consumption.

finds

Resource-utilization monitoring and alerting on bottlenecks or overloads limits the impact of denial-of-service or resource-exhaustion attacks.

prevents

By continuously monitoring utilization, stress-testing peak loads, and maintaining documented plans to scale or throttle resources, the control directly limits an attacker’s ability to drive a system into uncontrolled resource exhaustion.

finds

Pre-agreed severity-based prioritization and resource allocation during incident triage reduce the likelihood that an attacker-induced resource exhaustion will overwhelm the organization before corrective action is taken.

mitigates

Business-continuity plans that include resource-management controls reduce the likelihood that an attacker can trigger uncontrolled resource consumption by forcing the system into a degraded or fallback state.

mitigates

Defining RTOs and capacity requirements for ICT services during business-impact analysis forces organizations to provision sufficient resources and throttling mechanisms, reducing the likelihood that an attacker can induce denial-of-service through uncontrolled resource consumption.

finds

Early notification of anomalous resource consumption or system malfunctions enables throttling or isolation before availability is lost.
