CVE-2026-24218

HIGH 8.1

Published 2026-05-20 · Last modified 2026-05-21

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.
