A newly discovered critical vulnerability in the NVIDIA Container Toolkit threatens the security of AI applications across both cloud and on-premise environments. Tracked as CVE-2024-0132, this security flaw could allow adversaries to perform container escape attacks, gaining full access to the host system. Once compromised, an attacker could execute malicious commands or exfiltrate sensitive data, posing a significant risk to organizations using NVIDIA-powered GPU resources.
Overview of the Vulnerability
The vulnerability affects NVIDIA Container Toolkit versions 1.16.1 and earlier, as well as GPU Operator versions 24.6.1 and older. These are widely used across AI-focused platforms and virtual machine images to manage GPU access. The flaw, assigned a critical severity score of 9.0, arises from insufficient isolation between containerized GPUs and the host system, which can be exploited to break out of the container’s boundaries and gain unauthorized control over the host.
According to security researchers from Wiz Research, this issue could impact more than 35% of cloud environments that rely on NVIDIA's tools to manage GPU resources. The attack could be initiated either directly, via shared GPU resources, or indirectly, by tricking victims into running a malicious container image from an untrusted source.
How the Vulnerability Works
The primary issue with CVE-2024-0132 lies in the improper isolation of containerized GPU resources from the host system. Specifically, the flaw allows containers to mount sensitive parts of the host’s filesystem and access critical runtime resources, such as Unix sockets (e.g., docker.sock and containerd.sock) used for inter-process communication.
Although most filesystems are mounted with "read-only" permissions, these Unix sockets remain writable, providing an attacker with an opportunity to interact with the host system directly. Through a specially crafted container image, the attacker could execute commands on the host, escalate privileges, or steal sensitive information.
Discovery and Response
Wiz Research uncovered the vulnerability on September 1st, 2024, and promptly reported it to NVIDIA. The company quickly acknowledged the issue and released a fix on September 26th, 2024. The fix addresses the insecure interaction between containers and the host by strengthening the isolation of GPU resources, preventing unauthorized access to runtime components like Unix sockets.

Impacted users are strongly advised to upgrade to NVIDIA Container Toolkit version 1.16.2 and NVIDIA GPU Operator version 24.6.2 to mitigate the risk posed by this vulnerability.
Mitigation Steps
To protect AI applications and systems relying on NVIDIA GPU resources, it is crucial for organizations to implement the following mitigations:
While the technical details of the exploit are currently being withheld to allow organizations time to patch their systems, Wiz researchers plan to release more information in the coming weeks.
Conclusion
CVE-2024-0132 represents a significant threat to AI environments leveraging NVIDIA GPU resources. The potential for container escape and host compromise highlights the importance of maintaining secure isolation between containers and the host system. By promptly applying NVIDIA's security patch and following best practices for container security, organizations can reduce the likelihood of this vulnerability being exploited in their environments.
With more technical details on the way, it is essential for businesses to stay vigilant and ensure their systems remain up to date to mitigate any further risks.
