A critical vulnerability in Nvidia Container Toolkit, identified as CVE-2024-0132, has been discovered by cybersecurity researchers at cloud security startup Wiz.
According to researchers, this flaw affects artificial intelligence (AI) applications in cloud and on-premises environments that use graphics processing unit (GPU) resources, allowing attackers to escape container and desktop environments. take full control of the host system. This access could allow them to execute commands or exfiltrate sensitive data.
The Nvidia Container Toolkit is widely used on AI-focused platforms and virtual machine images, especially those involving Nvidia hardware. According to Brilliant researchthe vulnerability affects more than 35% of cloud environments. The discovery of this flaw raises concerns for any AI application that relies on the toolkit to enable GPU access.
On September 26, Nvidia released a security bulletin along with a patch to resolve the issue. Wiz Research, which identified the flaw, noted that the GPU company “worked with us throughout the disclosure process.” Organizations using the toolkit are advised to upgrade to version 1.16.2 immediately, focusing on hosts that may be running untrusted container images, as these are particularly vulnerable.
This vulnerability allows an attacker to escape the container and gain full access to the host system, posing serious risks to sensitive data and infrastructure. The risk is increased in environments that allow the use of third-party container images, as attackers could exploit this vulnerability via a malicious image.
In shared compute setups like Kubernetes (K8s), an attacker could escape from a container and access the data and secrets of other applications running on the same node or cluster, potentially compromising the entire environment.

The Nvidia Container Toolkit facilitates access to the GPU in containerized applications and has become a standard tool in the AI industry. The vulnerability extends to the Nvidia GPU operator, which manages the toolkit in Kubernetes environments. This expands the risk in various organizations using GPU-enabled containers.
All versions of Nvidia Container Toolkit up to and including v1.16.1, as well as Nvidia GPU Operator up to and including v24.6.1, are affected by this vulnerability. Use cases involving the Container Device Interface (CDI) are not affected.
To mitigate the risk created by the vulnerability, organizations should upgrade to the latest versions: Nvidia Container Toolkit v1.16.2 and Nvidia GPU Operator v24.6.2. Patching should be prioritized for hosts running untrusted container images or vulnerable versions of the toolkit. Additional protection can be achieved through runtime validation to confirm where the toolkit is used, according to Wiz.
The vulnerability can be exploited via various attack vectors, including social engineering, supply chain attacks on container image repositories, or environments that allow external users to load arbitrary container images. Although exposure to the Internet is not necessary for an attack to occur, attackers can still attempt to use malicious images through indirect methods such as social engineering.
Wiz Research’s investigation of AI service providers led to the discovery of this vulnerability, initially driven by questions about whether shared GPU resources could expose customer data to attacks. This prompted further exploration of Nvidia’s GPU-related tools, resulting in the identification of this significant security flaw.
Organizations that rely on Nvidia Container Toolkit are strongly encouraged to take immediate action by applying patches to avoid potential exploitation of their systems.
Nvidia’s continued dominance in the AI chip market
Earlier this year, Nvidia CEO Jensen Huang introduced several new products, describing the company’s position in an evolving technology landscape as part of a “new industrial revolution.” At Nvidia’s GPU Tech Conference (GTC)Huang announced the GB200, featuring two Blackwell graphics processing units (GPUs) and one Grace central processing unit (CPU), which have fueled the growth of generative AI.
The GB200 will power Nvidia’s Blackwell AI computing system, designed for AI models with billions of parameters to enhance generative AI capabilities. Huang noted that Blackwell GPUs, with 208 billion transistors, offer a major breakthrough in computing power, performing certain tasks up to 30 times faster than the H100 GPU. Companies like Amazon, Google, Microsoft and OpenAI are expected to use the chip in their cloud services and AI applications.
