KB5002273 is a Security Update for the 32-bit and 64-bit editions of Microsoft Office 2016, shipped in the July 2026 Patch Tuesday cycle. Details are provisional: Microsoft has not yet published the per-update CVE breakdown, so the specific flaws and their severity for this Office 2016 package are not confirmed, though the release document maps no named zero-days to it. Anyone still running Office 2016 desktop installs is in scope, and Office file-parsing bugs are commonly weaponized through email attachments.

Do this: Stage KB5002273 to a pilot ring of Office 2016 machines now, then check MSRC for the per-update CVE detail before broad deployment.
