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

In August 2026, researchers from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) disclosed a novel attack technique named 'Interrupt Injection.' This method exploits a timing vulnerability in Intel and AMD CPUs, allowing unprivileged Linux programs to inject hardware interrupts precisely between the processor's branch predictor sanitization and its subsequent use by the kernel. This re-poisoning of the branch predictor can lead to speculative execution vulnerabilities, enabling attackers to leak arbitrary kernel memory. Demonstrations on AMD Zen 2 processors running Linux 6.14 with default Spectre v2 mitigations showed data leakage rates of 5.47 bytes per second with 91.97% accuracy, sufficient to extract sensitive files like /etc/shadow in multiple attempts. The attack requires only local code execution without elevated privileges, posing significant risks to shared systems utilizing affected processors. This incident underscores the persistent challenges in securing speculative execution mechanisms within modern CPUs. Despite existing mitigations for Spectre v2 vulnerabilities, the discovery of Interrupt Injection highlights the need for continuous vigilance and adaptation in hardware and software defenses. Organizations must stay informed about emerging threats and ensure timely application of patches to protect sensitive data from sophisticated side-channel attacks.
