CVE-2025-23261

Password-hash disclosure via unsuppressed log entries

Published Sep 4, 2025 · Updated Sep 4, 2025

Sensitive information exposure in NVIDIA Cumulus Linux and NVOS allows local users to obtain hashed passwords from log files. The products fail to suppress hashed user-password values when writing log entries, leaving reusable password-verifier material in locally accessible records. Exploitation requires low-privileged local access, and the documented consequence is disclosure of password hashes rather than plaintext passwords or direct system modification.
