Hey there, it's me again! I found some security update news about Amazon RDS for SQL Server, and I want to share it with you!

What was announced?

According to AWS What's New, Amazon RDS for SQL Server now supports the latest Cumulative Updates (CU) and General Distribution Release (GDR) updates for Microsoft SQL Server. This covers a total of five versions, from SQL Server 2016 all the way to the newest SQL Server 2025!

The story so far

Amazon RDS for SQL Server has kept up with Microsoft's regular CU and GDR releases by rolling out matching patches. If you stay on an older version, you could remain exposed to the vulnerabilities that this round of GDR updates addresses, so keeping up with these releases really matters.

What changes

The highlight of this update is the vulnerability fixes delivered through the GDR updates. Four CVEs are addressed: CVE-2026-47295, CVE-2026-47296, CVE-2026-54118, and CVE-2026-55002. If you run RDS for SQL Server, you can apply these fixes by upgrading your instance through the Amazon RDS Management Console, the AWS SDK, or the CLI.
