CVE-2026-24185

Privilege escalation via alternate SSH auth path

Published Aug 18, 2026 · Updated Aug 18, 2026

Authentication bypass in the SSH server configuration component in NVIDIA NVOS allows remote authenticated users to gain elevated access via an alternate SSH path. When PKA-only mode is enabled, NVOS can expose a second SSH authentication route during administrator operations on the certificate list, so an unchanged default password remains usable despite the intended key-only setting. Exposure is limited to systems using PKA-only mode, and the consequence is unauthorized elevated access rather than disclosed code execution or a broader unauthenticated compromise.
