KB5002886 is a Security Update for Microsoft Excel 2016 in both 32-bit and 64-bit editions, shipped in the July 2026 Patch Tuesday cycle. Anyone running standalone or Office suite installs of Excel 2016 is exposed, and because CVE details for this cycle are still provisional, you cannot yet scope the exact vulnerabilities from Microsoft's per-update documentation. No named zero-days map to this Excel update, so it can be scheduled with your normal Office patching rather than as an emergency.
Do this: Deploy KB5002886 to all Excel 2016 (32-bit and 64-bit) endpoints in your next Office patch ring, and revisit the CVE detail once Microsoft publishes it to confirm scope.
