A newer security update for Windows 10 Version 1809 for 32-bit Systems has shipped since this one: KB5094041 (2026-08-11).

Senserva AI Opinion for KB5039227

KB5039227 delivers the same fix for CVE-2024-38213 to a different Windows 10 1809/Windows Server 2019 servicing branch as KB5039217, again Medium severity at CVSS 6.5, 13 percent EPSS, but already listed in CISA's KEV catalog. Because Microsoft ships this fix across several parallel builds this month, confirm your specific branch is one of the covered KBs rather than assuming a sibling patch already closed it. The KEV listing is the reason to move on this now rather than batching it with routine Medium-severity work.

Do this: Confirm your Windows 10 1809/Server 2019 branch received KB5039227 or one of its sibling builds that closes CVE-2024-38213.
