Hello community,

 

I found that article today: https://www.ixbt.com/news/2021/05/02/pod-ugrozoj-snova-milliardy-pk-v-processorah-amd-i-intel-najdena-novaja-ujazvimost.html

Thanks.

In my mind, there is nothing earthshattering here. There are a number of these theoretical exploits that leak data. Whether anyone can consistently use any of these exploits to get specifically actionable data is the big question. In most cases, the data leaked is so random that it is unusable. Still,...
