KB5053995: Windows Server 2019 Security Update (March 2025)
KB5053995 is a High security update for Windows Server 2019, released 2025-03-11. It closes 19 CVEs with a maximum CVSS of 8.8. At least one of them is actively exploited (CISA KEV) and linked to ransomware, so this is a deploy-first update. Get it from the Microsoft Update Catalog below, and see where it sits against the rest of the month on the patch tracker.
Microsoft security update released 2025-03-11. Fixes 19 CVEs.
Exploitation is not theoretical here: at least one CVE this update fixes is on the CISA Known Exploited Vulnerabilities catalog, which means attackers are already using it against unpatched systems, including in ransomware campaigns. For an update like this, the risk window is the gap between today and the day your last device installs it, so shortening that gap matters more than perfect scheduling.
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, including how to expedite it for the exploited CVE. For the bigger picture: how the Microsoft patching tools fit together, this month's Patch Tuesday summary, and every update ranked by real-world risk.
Updated July 24, 2026. Data refreshed on every build from MSRC, CISA KEV, and FIRST EPSS.

Update summary
Senserva AI Opinion for KB5053995
KB5053995 is the counterpart March 2025 update for the same Windows 10 1809 and Server 2019 population, fixing the identical 19-CVE set as KB5053888, including the ransomware-linked, CISA-KEV-listed flaws and the 32 percent EPSS score. Having two KBs for the same servicing branch this month usually means different update channels reaching the same machines, so admins need to make sure one of the two actually gets installed. Skipping both leaves the ransomware-associated exposure open.
Do this: Verify which of KB5053888 or KB5053995 your deployment ring received, and reconcile so no Windows 10 1809 or Server 2019 host is left on neither.

How to install KB5053995
Any of these paths delivers KB5053995; 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. For this update, consider an expedite policy: it bypasses deferrals for exactly this fix-now case.
- Windows Autopatch: rings, rollout, and pause or rollback are managed for you; exploited updates can be expedited.
- WSUS / Configuration Manager: approve KB5053995 for your device groups and set a deadline (deadline, not just approval, for an exploited fix).
- 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 KB5053995, ranked by exploitation.
Common questions about KB5053995
Does KB5053995 have known issues?
Yes. Microsoft's support article documents known issues for KB5053995 (checked 2026-07-22). The Known issues section on this page quotes it; verify against the article before acting.
Is KB5053995 urgent?
Yes. KB5053995 fixes at least one vulnerability in the CISA Known Exploited Vulnerabilities catalog, meaning attackers are using it in the wild, including in ransomware campaigns. Deploy it first.
How do I download KB5053995?
From the Microsoft Update Catalog (linked on this page), or let Intune, Windows Update for Business, Windows Autopatch, or WSUS deliver it. The catalog page lists the download for each supported product.
How do I deploy KB5053995 with Intune?
Assign a Windows Update ring (quality update policy) to the device groups and the update flows on the ring's deferral schedule. Because KB5053995 fixes an actively exploited CVE, an Intune expedite policy is the right tool: it bypasses configured deferrals and pushes the update as soon as devices check in. Verify the rollout with update compliance reporting rather than assuming delivery.
Can I ask my own AI about KB5053995?
Yes. This page includes a free, ready-to-paste AI prompt containing KB5053995's key facts: severity, CVE count, exploitation status, and the download link. Copy it into Claude, ChatGPT, or Copilot for a rollout plan; the data is refreshed three times a day (5 AM, 12:30 PM, and 7 PM US Central).
