Interrupt Injection Attack Bypasses Spectre v2 Defenses on Intel, AMD CPUs
Researchers have uncovered a shocking vulnerability that allows an unprivileged local program to bypass Spectre v2 defenses on Intel and AMD CPUs, leaking kernel memory with alarming speed and accuracy. On an AMD Zen 2 system, this exploit can siphon off sensitive data at a rate of 5.47 bytes per second with near 92% accuracy, making it possible to crack even highly secured files like /etc/shadow.
