Cumulative Update 3 (CU3) for Microsoft SQL Server 2017 was also released in the January 3, 2018, SQL Server Security Bulletin ADV180002. See KB 4058562 for more information. In other words, the same physical package (SQLServer2017-KB4052987-x64.exe) was made available both as CU3 (KB 4052987) and the Security Bulletin (KB 4058562).
Because of this, you may already have CU3 installed as part of that security release. If you do try to install CU3 after ADV180002, you may receive the following message:
This article describes Cumulative Update package 3 (CU3) for Microsoft SQL Server 2017. This update contains fixes that were released after the initial release of SQL Server 2017 and updates the SQL Server and Analysis services components to the following builds:

Cumulative updates (CU) are now available at the Microsoft Download Center.
Only the most recent CU that was released for SQL Server 2017 is available at the Download Center.
CU packages for Linux are available at https://packages.microsoft.com/.
- Each new CU contains all the fixes that were included in the previous CU for the installed version of SQL Server.
- SQL Server CUs are certified to the same levels as Service Packs, and should be installed at the same level of confidence.
- Microsoft recommends ongoing, proactive installation of CUs as they become available:
- Historical data shows that a significant number of support cases involve an issue that has already been addressed in a released CU.
- CUs may contain added value over and above hotfixes. This includes supportability, manageability, and reliability updates.
- We recommend that you test CUs before you deploy them to production environments.
How to obtain this CU package for Windows
If the download page does not appear, contact Microsoft Customer Service and Support to obtain the cumulative update package.
Note After future cumulative updates are released for SQL Server 2017, this CU can be located and downloaded from the Microsoft Windows Update Catalog. However, Microsoft recommends that you install the latest cumulative update available.

- Install the service pack on the active node (requires a service restart).
- Upgrade and update of availability group servers that use minimal downtime and data loss.
Note If you enabled AlwaysOn with SSISDB catalog, see information about SSIS with AlwaysOn for more information about how to apply a CU or SP in these environments.
