CVE-2025-23266

NVIDIA Container Toolkit for all platforms contains a vulnerability in some hooks used to initialize the container, where an attacker could execute arbitrary code with elevated permissions. A successful exploit of this vulnerability might lead to escalation of privileges, data tampering, information disclosure, and denial of service.

CVE-2025-23266 has a CVSS score of 9.0 (Critical). The vector is reachable from an adjacent network, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (1.17.8, 0.17.3, 25.3.2, 0.12.2); upgrading removes the vulnerable code path.

2. How severe is CVE-2025-23266? CVE-2025-23266 has a CVSS score of 9.0 (Critical). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which packages are affected by CVE-2025-23266?
   • github.com/NVIDIA/nvidia-container-toolkit (go) (versions < 1.17.8)
   • github.com/NVIDIA/k8s-device-plugin (go) (versions < 0.17.3)
   • github.com/NVIDIA/gpu-operator (go) (versions < 25.3.2)
   • github.com/NVIDIA/mig-parted (go) (versions < 0.12.2)
4. Is there a fix for CVE-2025-23266? Yes. CVE-2025-23266 is fixed in 1.17.8, 0.17.3, 25.3.2, 0.12.2. Upgrade to this version or later.
5. Is CVE-2025-23266 exploitable, and should I be worried? Whether CVE-2025-23266 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2025-23266 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2025-23266?
   • Upgrade github.com/NVIDIA/nvidia-container-toolkit to 1.17.8 or later
   • Upgrade github.com/NVIDIA/k8s-device-plugin to 0.17.3 or later
   • Upgrade github.com/NVIDIA/gpu-operator to 25.3.2 or later
   • Upgrade github.com/NVIDIA/mig-parted to 0.12.2 or later
