New AMD Side Channel Attacks Discovered, Impacts Zen Architecture (archive)
A new paper released by the Graz University of Technology details two new "Take A Way" attacks, Collide+Probe and Load+Reload, that can leak secret data from AMD processors by manipulating the L1D cache predictor. The researchers claim that the vulnerability impacts all AMD processors from 2011 to 2019, meaning that the Zen microarchitecture is also impacted. (PDF)
The university says it disclosed the vulnerabilities to AMD on August 23, 2019, meaning it was disclosed in a responsible manner (unlike the CTS Labs debacle), but there isn't any word of a fix yet. We've pinged AMD for comment.
We've become accustomed to news of new Intel vulnerabilities being disclosed on a seemingly-weekly basis, but other processor architectures, like AMD and ARM, have also been impacted by some vulnerabilities, albeit to a lesser extent. It's hard to ascertain if these limited discoveries in AMD processors are triggered by a security-first approach to hardened processor design, or if researchers and attackers merely focus on Intel's processors due to their commanding market share: Attackers almost always focus on the broadest cross-section possible. We see a similar trend with malware being designed for Windows systems, by far the predominant desktop OS, much more frequently than MacOS, though that does appear to be changing.

I'd say, this kind of impact is somewhat far from 'constipation' you describe.

Also, in other languages, the word 'afekt' or 'affect' is rather associated with a description of acute emotional instability of a person. Example: Zavraždila ho, protože byla v afektu.
It is the English language what is badly broken here, since Shakespeare's times. Shift of meanings by false politeness, political correctness, and hiding facts from attendant servants in salon conversations are the main cause of this cultural distortion of language.

The word affect has three different etymologies, and the meaning you ascribe to it comes from a different etymology to the meaning I am using. It is unfortunate that English has seen fit to spell this particular pair of different words in the same way, but they are pronounced differently in English - specifically: /ə.ˈfɛkt/ and /ˈæ.fɛkt/.

Maybe these processor architectures are blocked up with shit? Did you think about that?

I've always wanted to perform a manual disimpaction.
