What is CVE-2025-23359?

CVE-2025-23359 is a vulnerability found in the NVIDIA Container Toolkit for Linux, a tool designed to simplify the deployment of GPU-accelerated containers. This vulnerability stems from a Time-of-Check Time-of-Use (TOCTOU) flaw when the toolkit is used with its default settings. If an attacker creates a malicious container image, they could exploit this vulnerability to gain unauthorized access to the host file system. Such access can lead to severe consequences for organizations, including unauthorized execution of code, system outages, and potential breaches of sensitive information.

Technical Details

The CVE-2025-23359 vulnerability is characterized by a TOCTOU vulnerability that occurs when an application's security check fails to account for changes that may occur after the check has been completed but before a resource is actually used. In this context, a crafted container image can manipulate this timing window to execute unintended commands or access restricted areas of the file system. The default configuration of the NVIDIA Container Toolkit may inadvertently facilitate such exploitative maneuvers, thus compromising system integrity and security.

Potential Impact of CVE-2025-23359

  1. Code Execution: The vulnerability gives attackers the potential to execute arbitrary code on the host system, which can lead to total compromise of the system and its resources.

  2. Denial of Service: By leveraging this vulnerability, malicious actors can render services unavailable, causing disruptions to business operations and potential financial loss.

  3. Information Disclosure and Data Tampering: Attackers could gain access to sensitive data stored on the host system, leading to unauthorized disclosure or alteration of critical information, undermining data integrity and confidentiality.

Affected Version(s)

Container Toolkit Linux All versions up to and including 1.17.3

GPU Operator Linux All versions up to and including 24.9.1
