Update summary
Fixes 1 CVE. Most severe CVSS 8.8 (High). EPSS exploit probability up to 1.1%. 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.
KB5068402 is a November 11, 2025 GDR update patching CVE-2025-59499, a High severity flaw (CVSS 8.8) in the SQL Server database engine across the 2016 SP3, 2017, and 2019 x64 builds. Anyone running these older SQL Server versions is exposed, though the 1% EPSS and absence from CISA KEV suggest exploitation is not yet observed in the wild.
Do this: Apply the correct GDR package for your specific SQL Server version (2016 SP3, 2017, or 2019) after confirming your servers are on the GDR branch and not a Cumulative Update branch.
