7.5

OneFlow · OneFlow

A device-ID validation flaw in the OneFlow flow.cuda.get_device_capability() component allows unauthenticated attackers to cause a Denial of Service.

Executive summary

The OneFlow deep learning framework contains a critical device-ID validation vulnerability that allows unauthenticated remote attackers to trigger a Denial of Service on affected systems.

Vulnerability

This vulnerability is a Denial of Service flaw located within the flow.cuda.get_device_capability() function. It allows any unauthenticated attacker to crash the service by providing a specially crafted device ID.

Business impact

Successful exploitation of this vulnerability results in an immediate loss of service availability for the OneFlow framework. Given the CVSS score of 7.5, this high-severity flaw poses a significant operational risk to environments relying on OneFlow for critical AI or machine learning workloads, potentially disrupting automated pipelines and data processing tasks.

Remediation

Immediate Action: Monitor the OneFlow project repository for an official patch release, as no fix is currently available for version 0.9.0. In the interim, restrict network access to the OneFlow service to trusted internal segments only.

Proactive Monitoring: Review system and application logs for unusual crashes or repeated attempts to pass unexpected arguments to the cuda.get_device_capability function.

Compensating Controls: Deploy network-level access controls or an application-layer firewall to filter traffic to the OneFlow environment, ensuring that only authorized services can communicate with the vulnerable component.

Exploitation status

Public Exploit Available: Unknown

Analyst recommendation

Due to the high severity of this Denial of Service vulnerability, it is imperative that organizations using OneFlow v0.9.0 restrict exposure of the service immediately. Security teams should track the referenced GitHub issue for updates and prioritize the implementation of the vendor patch as soon as it becomes available to restore system stability and security.
