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.

addresses: CWE-400

Limiting concurrent sessions directly prevents uncontrolled resource consumption by capping the number of active sessions per user or account.

addresses: CWE-400

Analysis identifies uncontrolled resource consumption indicative of denial-of-service or abuse attempts.

addresses: CWE-400

Contingency plan testing includes resource exhaustion scenarios to verify recovery, making it harder for attackers to sustain exploits that cause uncontrolled consumption.

addresses: CWE-400

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.

addresses: CWE-400

Alternate site allows resumption of operations if resource exhaustion at the primary site is exploited to cause unavailability.

addresses: CWE-400

Alternate telecommunications services enable resumption of essential functions when primary services become unavailable due to uncontrolled resource consumption.

addresses: CWE-400

The team can analyze and respond to resource exhaustion incidents, reducing the impact of attacks that exploit uncontrolled consumption weaknesses.

addresses: CWE-400

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

T1499.004 Application or System Exploitation Impact
Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users.
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.
