SQL Server has an update that fixes several vulnerabilities, for all modern versions, from SQL Server 2014 SP3 right on up to SQL Server 2022. (If you're on SQL Server 2012 or worse, sorry, you're out of luck.)
This is technically a GDR, but there are different updates depending on whether you want to stay out of the Cumulative Update (CU) train (which I really don't recommend).
Go get it! (Or just go through Windows Update, as you're probably behind on those, too.) The download links point to Windows; if you're on Linux, see the instructions on the relevant KB article.
