Microsoft released an out-of-band update to fix a faulty April 2026 security update (KB5082063) that caused LSASS crashes and repeated restarts on Domain Controllers in multi-domain forests using Privileged Access Management, potentially rendering domains unavailable; the issue affected Windows Server 2016 through 2025 and hotpatches/updates were issued to restore authentication and directory services.
