The Security Update for SQL Server 2022 RTM CU8 is now available for download at the Microsoft Download Center and Microsoft Update Catalog sites. This package cumulatively includes all previous SQL Server 2022 fixes through CU8, plus it includes the new security fixes detailed in the KB Article.
I linked specifically to the SQL Server 2022 RTM CU8 blog post, but there are security bulletins for all versions of SQL Server going back to 2014. If you’re running SQL Server 2012 or earlier, no updates for you.
Also, the highest-risk CVE items are in SQL Server 2019 and 2022; for 2017 and below, the one security bulletin covers a moderate-severity denial of service attack.
