Here is the "canonical" question on the meltdown/spectre vulnerability on InfoSec.SE:
Can I/should I create a related question on dba.SE, perhaps something like, "As a SQL DBA, what do I need to know about the meltdown/spectre vulnerability?"
Do we even know, yet, how to contextualize this as a DBA?
Is this just yet another OS patch that we simply coordinate with the systems team to apply?
Are there patches available for MS SQL Server (or other products) required to address this vulnerability?
Any way of knowing what the performance impact might be for various kinds of (virtualized or bare-metal) SQL servers?
A couple of blog posts I've found that are starting to discuss this from a SQL server perspective:
- SQLHA: The No Good, Terrible Processor Flaw and SQL Server Deployments – Nearly Everything You Need To Know
- Thomas LaRock: SQL Server Guidance to Protect Against Meltdown and Spectre Attacks
- Brent Ozar: SQL Server Patches for Meltdown and Spectre Attacks
