CVE-2026-24185
NVIDIA NVOS SSH Server Authentication Bypass Vulnerability
Description
NVIDIA NVOS for network switches contains a vulnerability in the secure shell (SSH) server configuration component while PKA-only mode is enabled, where an administrator could inadvertently enable an alternative authentication path. If best practices for replacing the default password as recommended by NVIDIA are not followed, this alternative authentication path might lead to unauthorized access. A successful exploit of this vulnerability might lead to escalation of privileges.
