FKIE_CVE-2026-24218

Vulnerability from fkie_nvd - Published: 2026-05-20 20:16 - Updated: 2026-06-17 10:22
Severity
8.1 (High) - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
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.
