Ο Tavis Ormandy, ερευνητής ασφαλείας από την Google δημοσίευσε την ευπάθεια που ανακάλυψε σε συγκεκριμένους AMD Zen 2 επεξεργαστές. Επηρεάζει πλήθος επεξεργαστών Zen 2, ακόμη και τους AMD EPYC που χρησιμοποιούνται σε datacenters αλλά και τους Ryzen 3000/4000/5000 CPUs, επιτρέποντας την κλοπή σημαντικών πληροφοριών από τη CPU, όπως κλειδιών κρυπτογράφησης και user logins.
Δεν απαιτεί καν φυσική πρόσβαση στο PC και η επίθεση μπορεί να πραγματοποιηθεί μέσω javascript από μια ιστοσελίδα. Το Toms Hardware συνέθεσε μια λίστα με τους επεξεργαστές που επηρεάζονται και την αναμενόμενη ημερομηνία επιδιόρθωσης της ευπάθειας μέσω της διάθεσης του απαραίτητου λογισμικού.
