However they also claim the mitigation "reduces exposure to this vulnerability but cannot fully prevent it", without elaborating on what that means or how it would be possible... I've also not seen anyone else make this claim.
They did finally change their priority to critical though.
That's what I call Steve Jobs style PR / Marketing you deflect the problem by making another problem to make it seem like you're fully aware. "You're holding the phone wrong"
So far they're two days later than IBM/Red Hat. Not great, for sure, but they seem to be that far behind compared to the competition just yet.
If they push a backport that kills a million set top boxes because of changes in the network stack, they're not much better off than if they work a couple more days on testing.
