NVIDIA Infrastructure Controller Missing Authentication Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2026-65114

The NVIDIA Infrastructure Controller is a specialized component typically used within data center or server environments. While network-reachable, it is not a standard internet-facing service or edge gateway, making direct public internet exposure uncommon in typical deployments, though it remains a theoretical possibility depending on the specific network architecture.

Critical functions could be compromised.
Confirm relevance and exposure.

Attack Path

How an attacker could exploit the issue

An attacker could exploit this vulnerability by reaching a critical function within the NVIDIA Infrastructure Controller for Linux that lacks proper authentication. This could allow them to manipulate or expose sensitive data, or disrupt system operations.

Unauthenticated network access required.
Critical function call.
Data tampering, denial of service, information disclosure.

Live Threat

Current exploitation, exposure, and threat context

When supported by the advisory, an attacker could exploit a missing authentication flaw in NVIDIA Infrastructure Controller for Linux to tamper with data, disrupt services, or disclose information.

Critical infrastructure data or service integrity.
Unauthenticated network access to critical functions.
Potential for unauthorized data manipulation or service disruption.

Operational Fix

Recommended remediation, mitigation, and detection steps

Teams responsible for managing NVIDIA Infrastructure Controller for Linux deployments, likely platform or infrastructure teams, should prioritize identifying all instances of this software. The initial focus should be on confirming whether these systems are exposed to the network, assessing their criticality to business operations, and then locating the accountable owner to plan remediation based on the potential impact of data tampering, denial of service, or information disclosure.

Identify controller instances and exposure.
Confirm business criticality and ownership.

Frequently asked questions

What is the NVIDIA Infrastructure Controller?

It is a specialized hardware-management component designed for data center and server environments. It handles low-level infrastructure tasks, often managing system-level communications and resources to ensure high-performance operations in complex networking environments.

What does CWE-306 mean for CVE-2026-65114?

CWE-306 refers to Missing Authentication for a Critical Function. In this case, it means the software fails to verify who is sending a command before executing a sensitive task. Because the controller skips this check, unauthorized parties can interact with functions meant only for verified administrators, leading to unintended system changes or data exposure.

How does an attacker trigger this vulnerability?

The flaw is triggered when an attacker sends a request over the network to a sensitive function that lacks access controls. It is not triggered by local, authenticated system tasks or standard user-level applications that interact with the controller through legitimate, properly secured interfaces.

Is my system at risk according to Halo Surface Signal?

Halo Surface Signal notes that while the controller is network-reachable, it is not typically an internet-facing service like a web browser or gateway. Risk depends on your specific network architecture; if the controller is accessible from public networks, the potential for unauthorized access is higher than if it is restricted to internal segments.

Do I need to update my NVIDIA Infrastructure Controller?

Yes, you should begin by creating an inventory of all instances running versions prior to 2.0.0. Once identified, evaluate the network accessibility of these systems and confirm their business role. Coordinate with the relevant infrastructure or platform owners to schedule updates and mitigate the risk of unauthorized access.
