Senserva AI Opinion for KB5046858

This SQL Server package fixes 31 CVEs from the November cycle, including CVE-2024-38255 and CVE-2024-43459, all reaching Severity High at CVSS 8.8, across the 2016, 2017, and 2019 branches. Given the CVE count, treat this as a major update requiring its own testing pass rather than a routine monthly patch. None of the 31 are currently in CISA KEV, which allows for a planned rather than emergency rollout.

Do this: Plan a dedicated testing pass for this 31-CVE SQL Server update before production rollout.

AI-generated from public data, 2026-07-07. Verify against the vendor advisory before acting.
