KB5040942: Microsoft SQL Server 2017 for x64-base Security Update (July 2024)
KB5040942 is a High security update for Microsoft SQL Server 2017 for x64-base, released 2024-07-09. It closes 36 CVEs with a maximum CVSS of 8.8. It is the eighth largest of the 32 updates Microsoft shipped that month, by CVEs closed.
Update summary
Fixes 36 CVEs. Most severe CVSS 8.8 (High). EPSS exploit probability up to 1.8%. Among the lower half of tracked Microsoft updates by EPSS exploit probability.
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.
KB5040942 is the July 2024 GDR rollup for SQL Server 2016 SP3, 2017, and 2019, closing 36 CVEs at a highest Severity of High with a CVSS of 8.8. Most of these are SQL Server engine flaws (for example CVE-2024-38088 and CVE-2024-37318), so any host running a database instance under these versions is in scope. None are on the CISA KEV list and EPSS tops out at 2%, meaning there is no evidence of active exploitation yet, but the count of 36 fixes makes this a substantial single-shot patch.
Do this: Schedule the GDR update across your SQL Server 2016 SP3, 2017, and 2019 instances during your next maintenance window, prioritizing internet-facing or business-critical database hosts first.
