TONTOU: On the Exploitability of Time-of-Neutralization to Time-of-Use Windows
Recently deployed Spectre v2 mitigations neutralize branch predictor state when switching privilege contexts or immediately prior to indirect branch execution, either through domain isolation or sanitization. These defenses assume that subsequent branch predictor behavior remains free from attack...

New Interrupt Injection Attack Can Bypass Spectre v2 Defenses on Intel and AMD CPUs
An unprivileged Linux program can time a hardware interrupt to land in the gap between a processor sanitizing its branch predictor and the kernel using it, re-poisoning the predictor after the defense has run. MIT CSAIL researchers Daniël Trujillo and Mengjia Yan named the technique INTERRUPT...
