CVE-2025-71004 identifies a vulnerability in the oneflow.logical_or component of OneFlow version 0.9.0, a machine learning framework. The vulnerability manifests as a segmentation violation, which is a type of memory safety error that can occur due to null pointer dereferences (CWE-476), out-of-bounds reads (CWE-125), or buffer overflows (CWE-787). This flaw allows an attacker to cause a Denial of Service (DoS) by supplying specially crafted input that triggers the segmentation fault, crashing the process or causing it to become unresponsive. The CVSS v3.1 score of 6.5 (medium severity) reflects that the attack vector is network-based (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R), and impacts availability only (A:H) without affecting confidentiality or integrity. The vulnerability does not require authentication, increasing its exposure risk. No patches or fixes are currently available, and no exploits have been observed in the wild. The vulnerability is relevant for users running OneFlow v0.9.0, particularly those deploying it in production environments for AI or data processing tasks. The segmentation violation could disrupt services relying on OneFlow, leading to downtime or degraded performance. Given the nature of the flaw, attackers cannot gain code execution or data access but can cause service interruptions. Organizations should monitor for updates from OneFlow maintainers and consider implementing input validation or sandboxing to mitigate impact until a patch is released.

For European organizations, the primary impact of CVE-2025-71004 is the potential for Denial of Service attacks against systems running OneFlow v0.9.0. This could disrupt AI workloads, data processing pipelines, or other critical services that depend on OneFlow, leading to operational downtime and productivity loss. Since the vulnerability does not affect confidentiality or integrity, data breaches or manipulation are unlikely. However, availability disruptions can have significant consequences in sectors relying on real-time analytics or automated decision-making, such as finance, healthcare, and manufacturing. The requirement for user interaction slightly reduces the risk but does not eliminate it, especially in environments where users might process untrusted data inputs. The lack of known exploits in the wild provides some relief, but the absence of patches means organizations remain exposed. European entities with cloud deployments or AI research centers using OneFlow are particularly at risk. The vulnerability could also affect service providers offering AI-as-a-service if they use vulnerable versions, potentially impacting their European customers indirectly.

1. Monitor official OneFlow repositories and security advisories for patches addressing CVE-2025-71004 and apply updates promptly once available. 2. Implement strict input validation and sanitization on all data fed into the oneflow.logical_or component to prevent malformed inputs from triggering the segmentation fault. 3. Restrict network access to OneFlow services to trusted users and systems only, using firewalls and network segmentation to reduce exposure. 4. Employ sandboxing or containerization to isolate OneFlow processes, limiting the impact of potential crashes on the broader system. 5. Incorporate runtime monitoring and automated restart mechanisms to quickly recover from unexpected service interruptions caused by DoS attempts. 6. Educate users and administrators about the risks of processing untrusted inputs and encourage cautious handling of external data sources. 7. Conduct regular security assessments and penetration testing focusing on AI frameworks and their components to detect similar vulnerabilities proactively.
