Microsoft security update released 2026-07-14. Fixes 4 CVEs.
No exploitation is confirmed for the CVEs in this update and the EPSS exploitation probability is currently 1.3%. That can change: CVEs from past updates regularly get exploited months later, which is why deploying on your normal cadence, without exceptions that linger, is what keeps this one boring.
SQL Server updates deploy per instance, usually via the downloaded package or your server patching tool rather than client update rings. The install guidance below covers the options. 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.

Update summary
Senserva AI Opinion for KB5102337
KB5102337 is Cumulative Update 31 for SQL Server 2017 on x64 systems, shipping as a Security Update in the July 2026 cycle. The MSRC release document maps no named zero-days to this update, and per-update CVE detail is still provisional because Microsoft has not published it for this cycle. Exposure is limited to database servers still running the SQL Server 2017 branch, which are often internally facing and less frequently patched than OS layers.
Do this: Inventory your SQL Server 2017 x64 instances and schedule CU 31 (KB5102337) through a test instance before applying to production database servers.

Known issues, from Microsoft
Quoted from Microsoft's support article for KB5102337 (checked 2026-07-21). Verify against the article before acting.
Linked server queries that use MSDASQL fail with error 7416
Linked server queries that use the MSDASQL (OLE DB Provider for ODBC Drivers) provider and specify a provider string (@ provstr ) fail and return the following error message:
Msg 7416, Level 16
Access to the remote server is denied because no login-mapping exists.
A stricter connection validation check in the Database Engine can reject connections for certain linked server configurations that use the MSDASQL provider, even if earlier builds allowed those connections.
For more information and workarounds, see Linked server queries that use MSDASQL fail with error 7416.
