Data Validation Flaw in NVIDIA TensorRT-LLM Affects Multiple Platforms

CVE-2025-23245

What is CVE-2025-23245?

CVE-2025-23245 is a vulnerability affecting NVIDIA's vGPU software, utilized on both Windows and Linux platforms. This software is designed to optimize GPU resource allocation among virtual machines, enhancing performance for applications requiring intensive graphical processing. The vulnerability arises from inadequate data validation in the Virtual GPU Manager, potentially allowing a guest system to gain unauthorized access to global resources. This exposure could have significant ramifications for organizations relying on this technology, as it may disrupt service availability and compromise system integrity.

Technical Details

The vulnerability occurs within the Virtual GPU Manager component of NVIDIA's vGPU software. It involves a flaw in how data is validated, which can lead to improper handling of requests from guest virtual machines. By exploiting this weakness, an attacker could manipulate the system, leading to potential resource misallocation and service interruptions. The underlying issue stems from oversight in resource access controls, demonstrating the need for robust validation mechanisms in multi-tenant environments.

Potential Impact of CVE-2025-23245

1. Denial of Service (DoS): Successful exploitation of this vulnerability can lead to denial of service, where legitimate users are unable to access necessary resources, significantly disrupting business operations.

2. Resource Misallocation: Attackers may gain unauthorized access to global resources, which could compromise the integrity and availability of critical applications running on affected systems.

3. Increased Vulnerability Surface: By exploiting this flaw, attackers may pave the way for further attacks on the infrastructure, potentially leading to larger-scale breaches or the installation of persistent threats.
