Branch Privilege Injection: Exploiting branch predictor race conditions (ethz.ch)
Branch Privilege Injection (CVE-2024-45332) brings back the full might of branch target injection attacks (Spectre-BTI) on Intel. Intel’s hardware mitigations against these types of attacks have held their ground for almost 6 years. In our work, we demonstrate how these mitigations can be broken due to a race condition in Intel CPUs.
