Senserva AI Opinion for CVE-2025-62554

Office LTSC 2024 is the notable name here: the newest perpetual-license Office, along with Office 2019 and Office for Android, carries this document remote code execution flaw. LTSC installs skip the Microsoft 365 update cadence, so they only get this fix if someone deploys it deliberately. EPSS is 0 percent.

Do this: Add Office LTSC 2024 machines to this month's patch scope explicitly rather than assuming channel updates cover them.
