Critical NVIDIA Container Toolkit Flaw Exposes AI Cloud Services to Privilege Escalation Attacks
A recently discovered vulnerability in the NVIDIA Container Toolkit has left managed AI cloud services exposed to severe attacks, allowing attackers to execute arbitrary code with elevated privileges. The bug, codenamed NVIDIAScape, carries a CVSS score of 9.0 out of 10.0 and affects all versions of NVIDIA Container Toolkit up to and including 1.17.7. This alarming discovery highlights the importance of prioritizing AI security risks and implementing robust isolation barriers in multi-tenant environments.
Cybersecurity researchers have identified a critical vulnerability in NVIDIA Container Toolkit that could lead to severe attacks on managed AI cloud services. The vulnerability, tracked as CVE-2025-23266, carries a CVSS score of 9.0 and has been codenamed NVIDIAScape. A successful exploit can result in a complete takeover of the server, allowing attackers to execute arbitrary code with elevated privileges. The vulnerability affects 37% of cloud environments and is considered "incredibly" easy to weaponize. Organizations should prioritize AI security risks and implement robust isolation barriers in multi-tenant environments. This discovery highlights the need for organizations to stay vigilant and proactive when it comes to AI security risks, especially as the tech stack continues to grow and evolve.
Cybersecurity researchers have sounded an alarm over a critical container escape vulnerability in the NVIDIA Container Toolkit, leaving managed AI cloud services vulnerable to severe attacks. The discovery, made by Google-owned cloud security company Wiz, has sent shockwaves through the cybersecurity community, highlighting the need for organizations to prioritize AI security risks and implement robust isolation barriers.
According to Wiz, the vulnerability, tracked as CVE-2025-23266, carries a CVSS score of 9.0 out of 10.0 and has been codenamed NVIDIAScape. The bug is attributed to a misconfiguration in how the NVIDIA Container Toolkit handles the Open Container Initiative (OCI) hook "createContainer." A successful exploit for this vulnerability can result in a complete takeover of the server, allowing attackers to execute arbitrary code with elevated privileges.
The implications of this discovery are far-reaching and severe. With a "stunningly simple three-line Dockerfile," an attacker can load their shared object file into a privileged process, resulting in a container escape that could compromise sensitive data and proprietary models of other customers running on the same shared hardware. This vulnerability affects 37% of cloud environments, making it a significant concern for organizations that rely on AI cloud services.
Wiz researchers Nir Ohfeld and Shir Tamari have characterized the flaw as "incredibly" easy to weaponize, citing the fact that an attacker can load their malicious library into the container by setting LD_PRELOAD in their Dockerfile. The vulnerability also stems from a misconfiguration in how the toolkit handles the createContainer hook, which executes with its working directory set to the container's root filesystem.
This discovery serves as a stark reminder of the importance of prioritizing AI security risks and implementing robust isolation barriers in multi-tenant environments. As Wiz notes, "containers are not a strong security barrier" and should not be relied upon as the sole means of isolation. Instead, organizations should assume that vulnerabilities exist and implement at least one strong isolation barrier, such as virtualization.
The NVIDIA Container Toolkit vulnerability is also part of a broader trend of discovering critical vulnerabilities in AI-related technologies. Just a couple of months ago, Wiz detailed a bypass for another vulnerability in the NVIDIA Container Toolkit (CVE-2024-0132, CVSS score: 9.0 and CVE-2025-23359, CVSS score: 8.3) that could have been abused to achieve complete host takeover.
This latest discovery highlights the need for organizations to stay vigilant and proactive when it comes to AI security risks. As Wiz notes, "old-school" infrastructure vulnerabilities in the ever-growing AI tech stack remain a significant threat that security teams should prioritize. By acknowledging this reality and taking proactive steps to address these vulnerabilities, organizations can reduce their risk exposure and protect themselves against potential attacks.
In conclusion, the critical NVIDIA Container Toolkit flaw exposes managed AI cloud services to severe privilege escalation attacks. The discovery serves as a stark reminder of the importance of prioritizing AI security risks and implementing robust isolation barriers in multi-tenant environments. As the AI tech stack continues to grow and evolve, it is essential for organizations to stay vigilant and proactive when it comes to addressing these vulnerabilities.
