Threat & Defense Details
Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Limiting concurrent sessions directly prevents uncontrolled resource consumption by capping the number of active sessions per user or account.
Analysis identifies uncontrolled resource consumption indicative of denial-of-service or abuse attempts.
Contingency plan testing includes resource exhaustion scenarios to verify recovery, making it harder for attackers to sustain exploits that cause uncontrolled consumption.
Updated contingency plans include current procedures to detect, contain, and recover from resource exhaustion, limiting an attacker's ability to sustain impact from uncontrolled consumption.
Alternate site allows resumption of operations if resource exhaustion at the primary site is exploited to cause unavailability.
Alternate telecommunications services enable resumption of essential functions when primary services become unavailable due to uncontrolled resource consumption.
The team can analyze and respond to resource exhaustion incidents, reducing the impact of attacks that exploit uncontrolled consumption weaknesses.
Timely maintenance support and spare parts enable rapid recovery from failures induced by uncontrolled resource consumption, shortening the impact window of denial-of-service attacks.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Direct mapping to application exploitation causing endpoint DoS via uncontrolled resource consumption from crafted input.
NVD Description
An issue in the flow.cuda.BoolTensor component of OneFlow v0.9.0 allows attackers to cause a Denial of Service (DoS) via a crafted input.
Deeper analysisAI
CVE-2025-71000 is a vulnerability in the flow.cuda.BoolTensor component of OneFlow version 0.9.0. The issue enables attackers to trigger a Denial of Service (DoS) condition by providing a crafted input. It carries 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), indicating high severity primarily due to its impact on availability, and is linked to CWE-400 (Uncontrolled Resource Consumption). The vulnerability was published on 2026-01-28.
Attackers can exploit this remotely over a network with low complexity, without requiring authentication, privileges, or user interaction. Successful exploitation results in high availability disruption, such as crashing the affected OneFlow process or causing significant resource exhaustion, while confidentiality and integrity remain unaffected.
