A newer security update for Microsoft SQL Server 2017 for x64-based Systems (GDR) has shipped since this one: KB5101346 (2026-07-14). For cumulative update families the newer package includes these fixes, so installing that one is usually the shorter path. Verify against your own update rings before you skip this package.

Senserva AI Opinion for KB5042578

This is another variant of the September SQL Server rollup, fixing the same eleven CVEs across the 2017 GDR, 2019 GDR, and 2017 CU 31 branches, with a top Severity of High at CVSS 8.8. Multiple near-identical KB numbers exist for this cycle because Microsoft ships separate packages per servicing branch and architecture. Match the package to your exact SQL Server version and branch rather than assuming any one KB covers everything.

Do this: Verify the exact SQL Server branch in use, then apply the matching September update to close the eleven CVEs.
