Senserva AI Opinion for KB5042749

Eleven CVEs are addressed in this SQL Server 2017 and 2019 package, topping out at Severity High, CVSS 8.8, as part of the September servicing wave. SQL Server database engines on the GDR and CU 31 branches are the exposed systems here, and none of the eleven CVEs currently show CISA KEV or ransomware activity. Treat this as routine but not optional patching for any production database tier.

Do this: Roll this SQL Server update out to production database servers on the 2017 or 2019 GDR and CU 31 branches.
