New Interrupt Injection Attack Can Bypass Spectre v2 Defenses on Intel and AMD CPUs

**Source : The Hacker News | 6 août 2026** 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 INJECTION. On an AMD Zen 2 machine running Linux 6.14 with every default Spectre v2 mitigation on, 👉 **Lire l'article complet sur The Hacker News :** [https://thehackernews.com/2026/08/new-interrupt-injection-attack-can.html](https://thehackernews.com/2026/08/new-interrupt-injection-attack-can.html)
