New Intel CPU side-channel attack Indirector can leak sensitive data

Researchers at the University of California San Diego have identified a new CPU security vulnerability called Indirector that takes advantage of the indirect branch predictor and branch target buffer in Intel chips to breach security boundaries and leak protected data. This advanced technique builds upon previous Spectre and Meltdown CPU attack insights, posing risks across processes and privilege levels with significant implications for OS security, particularly due to challenges in mitigating these attacks without serious performance trade-offs. Intel has responded with mitigations like the indirect branch predictor barrier (IBPB), but efficient and broadly effective solutions are yet to be fully realized.
