If you cannot patch yet, organizations should avoid deploying cloned base images with identical SSH host keys or manually regenerate unique SSH host keys on each provisioned system to mitigate the risk of host impersonation and related attacks.
Description
NVIDIA DGX OS has a vulnerability in its factory provisioning process where cloning a base image results in identical SSH host keys being deployed across multiple systems. This reuse of cryptographic identifiers allows potential host impersonation or man-in-the-middle attacks. Exploiting this vulnerability could lead to code execution, data tampering, privilege escalation, information disclosure, and denial of service. The vulnerability is tracked as CVE-2026-24218 with a high severity score of 8.1. There are no known exploits in the wild at this time.
