Lifecycle Timeline
2DescriptionCVE.org
A shape mismatch vulnerability in OneFlow v0.9.0 allows attackers to cause a Denial of Service (DoS) via supplying crafted tensor shapes.
Executive ViewAI
CVE-2025-65886 is a denial-of-service vulnerability affecting OneFlow v0.9.0 that allows attackers to crash services through malformed tensor inputs. Organizations using OneFlow in production environments face service disruption risks, particularly those processing untrusted machine learning model inputs or operating customer-facing ML inference services.
Implement strict input validation and sanitization for tensor shape parameters before processing; deploy rate limiting and request throttling on OneFlow API endpoints; segment OneFlow services behind network firewalls to restrict access to trusted sources only; monitor for abnormal tensor shape submissions and establish alerting; consider disabling OneFlow services in non-critical environments until patched; maintain service redundancy and failover mechanisms to mitigate DoS impact.
