Does SQL Server 2008R2 Security Update 10.50.6560.0 (Meltdown/Spectre) include the TLS1.2 update 10.50.6542.0?
I can see the TLS1.2 update is a lower build number, but I can't find anywhere that states that the higher update includes the lower one(s) - there's 3 others post SP3 too - as it's not listed as a rollup patch.
