From New RIDL and Fallout Attacks Impact All Modern Intel CPUs:


Multiple security researchers have released details about a new class of speculative execution attacks against most modern Intel processors. Called data-sampling attacks, they are different from and more dangerous than Meltdown, Spectre and their variations because they can leak data from CPU buffers, which is not necessarily present in caches.


Speculative execution is a method for optimizing the performance of a CPU by running tasks in advance, without knowing whether they will be needed or not.


As indicated in the Wired article at Intel Flaw Lets Hackers Siphon Secrets from Millions of PCs | WIRED, it is four distinct attacks using a similar technique, and all capable of siphoning a stream of potentially sensitive data from a computer's CPU to an attacker.
