 1. For MDS
 ~~~~~~~~~~
-Core scheduling cannot protect against MDS attacks between an HT running in
-user mode and another running in kernel mode. Even though both HTs run tasks
-which trust each other, kernel memory is still considered untrusted. Such
-attacks are possible for any combination of sibling CPU modes (host or guest mode).
+Core scheduling cannot protect against MDS attacks between the siblings
