what @Manu_PT try to explain is that current patch will become useless once the hackers(nsa) will manage to undo is effects and use the vulnerability again ... so we may have an endless release of patches(if hackers successful attack is discovered..) .... patching the previous patch without success as a soft patch can't fix a cpu architecture design which has a flaw (feature)...

That patch is in the operating system kernel. If an attacker can modify that to undo the effects, they have no need to use Meltdown in the first place.

Found this by digging the links:

@btarunr please update the image to reflect that the issue happens on older chipsets and/or add more information, Ryzen seems not to be affected so far. As it stands, it is vague and creates FUD around which AMD products this is being affected, with reports so far pointing to K8-era hardware. It is enough that this is already happening with Intel CPUs.

Minor edit for completeness.

Poor K8, it's not the first time MS doing security patches like this, i remember about 3 of this kind during 2008-2012...
