No exploitation is confirmed for the CVEs in this update and the EPSS exploitation probability is currently <1%. That can change: CVEs from past updates regularly get exploited months later, which is why deploying on your normal cadence, without exceptions that linger, is what keeps this one boring.
Most organizations deliver an update like this automatically through Intune update rings, Windows Update for Business, Windows Autopatch, or WSUS; the install section below covers each path.

Update summary
Senserva AI Opinion for KB5002819
Released in December 2025, KB5002819 patches two High severity flaws, CVE-2025-62554 and CVE-2025-62557, reaching up to CVSS 8.4, across Office LTSC 2024 (64-bit), Office 2019 (64-bit), and Office for Android. Neither CVE appears in CISA's Known Exploited Vulnerabilities list or ransomware tracking and EPSS is 0 percent, but this update spans both desktop LTSC builds and the Android mobile client, so mobile device management channels need the fix too, not just Windows endpoints.
Do this: Push KB5002819 through both desktop patch management and mobile device management for Office for Android users.

How to install KB5002819
Any of these paths delivers KB5002819; most organizations already have one of the first three running:
- Intune update rings (Windows Update for Business): the update flows on each ring's deferral schedule.
- Windows Autopatch: rings, rollout, and pause or rollback are managed for you; exploited updates can be expedited.
- WSUS / Configuration Manager: approve KB5002819 for your device groups and set a deadline.
- Manual: download from the Update Catalog above and install; fine for a handful of machines, unmanageable at any real scale.
After the rollout, verify rather than assume: update compliance reporting in Intune or Autopatch shows which devices actually installed it, and Siemserva reads Intune, Defender, Autopatch, and Azure Update Manager together to show the devices still missing KB5002819, ranked by exploitation.
