CVE-2025-40760

Password-hash disclosure via authentication error output

Published Nov 11, 2025 · Updated Nov 11, 2025

Information disclosure in Siemens Altair Grid Engine before 2026.0.0 allows local users to obtain privileged-account password hashes. The setuid-root authuser utility includes sensitive password-hash data in error output while processing authentication requests. Low-privileged local access is required, and the exposed hashes support offline brute-force attacks without reported integrity or availability impact.
