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 researchersDaniël Trujillo and Mengjia Yan named the technique INTERRUPT...

CVE-2026-64507

A flaw was found in the Linux kernel. This vulnerability involves an incomplete defense against Spectre-v2, a type of attack that can expose sensitive information by exploiting how modern processors predict future operations. Specifically, when the Berkeley Packet Filter BPF Just-In-Time JIT...

CVE-2026-64507

CVE-2026-64507 : In the Linux kernel, a hardening tied to Spectre-v2 mitigations enables an IBPB flush during BPF JIT allocation/memory reuse when BPF-JIT is in use. The change guards the IBPB enabling under CONFIG_BPF_JIT, and skips enabling if the BPF dispatcher already uses a retpoline sequenc...
