NVIDIA DGX OS SSH Host Key Duplication Vulnerability
CVE-2026-24218 Published on May 20, 2026
NVIDIA DGX OS contains a vulnerability in the factory provisioning process, where the cloning of a base image causes identical SSH host keys to be deployed across multiple systems. The sharing of cryptographic identifiers across all similarly provisioned systems enables host impersonation or attacker-in-the-middle attacks. A successful exploit of this vulnerability might lead to code execution, data tampering, escalation of privileges, information disclosure, and denial of service.
Vulnerability Analysis
CVE-2026-24218 is exploitable with network access, and does not require authorization privileges or user interaction. This vulnerability is consided to have a high level of attack complexity. The potential impact of an exploit of this vulnerability is considered to be very high.
Weakness Type
Use of Hard-coded Cryptographic Key
The use of a hard-coded cryptographic key significantly increases the possibility that encrypted data may be recovered.
Affected Versions
NVIDIA DGX Spark:- Before OTA0 is affected.
