CVE-2025-71005 identifies a floating point exception vulnerability in the oneflow.view component of OneFlow version 0.9.0. OneFlow is a machine learning framework used for efficient tensor computations and model training. The vulnerability arises from improper handling of floating point operations within the view component, which processes tensor reshaping and viewing operations. When an attacker supplies specially crafted input data that triggers this floating point exception (CWE-369), it causes the application to crash or become unresponsive, resulting in a denial of service (DoS) condition. The CVSS 3.1 score of 6.5 reflects a medium severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The scope remains unchanged (S:U), and the impact affects availability only (A:H), with no confidentiality or integrity impact. No known exploits have been reported in the wild, and no patches have been officially released yet. This vulnerability could be exploited remotely by sending malicious input to exposed OneFlow services or APIs that utilize the vulnerable component. The floating point exception likely results from edge cases in tensor dimension calculations or memory access during the view operation. This vulnerability highlights the importance of robust input validation and error handling in numerical computing frameworks to prevent service disruptions.

For European organizations leveraging OneFlow in AI, machine learning, or data processing pipelines, this vulnerability poses a risk of service outages due to denial of service attacks. Such disruptions could affect critical business operations, research activities, or cloud services relying on OneFlow, leading to productivity loss and potential financial impact. Although confidentiality and integrity are not directly compromised, availability degradation can indirectly affect trust and operational continuity. Organizations with public-facing APIs or services that process untrusted input using OneFlow are at higher risk. The medium severity indicates that while exploitation is feasible without privileges, it requires user interaction, somewhat limiting widespread automated attacks. However, targeted attacks against AI infrastructure in sectors like finance, healthcare, or manufacturing could cause significant operational interruptions. The lack of patches and known exploits means organizations must proactively implement mitigations to reduce exposure. Overall, the impact is primarily operational but could escalate if combined with other vulnerabilities or used as a distraction in multi-vector attacks.

1. Immediately restrict network exposure of OneFlow services, especially those using the oneflow.view component, to trusted internal users only. 2. Implement strict input validation and sanitization on all data fed into OneFlow tensor operations to prevent malformed or malicious inputs triggering floating point exceptions. 3. Monitor application logs and system metrics for signs of crashes or abnormal terminations related to tensor operations. 4. Employ runtime protections such as process isolation, resource limits, and watchdog timers to recover from unexpected crashes and maintain service availability. 5. Engage with OneFlow maintainers and security advisories to obtain patches or updates addressing this vulnerability as soon as they are released. 6. Consider deploying Web Application Firewalls (WAFs) or API gateways with custom rules to detect and block suspicious payloads targeting the vulnerable component. 7. Conduct internal security assessments and fuzz testing on OneFlow inputs to identify and remediate similar edge cases proactively. 8. Educate developers and data scientists on secure coding practices related to numerical computations and error handling in machine learning frameworks.
