Latest Intel CPUs impacted by new Indirector side-channel attack

**Executive summary:** Indirector is a newly described high-precision branch-target-injection (BTI) attack that leverages flaws in the Indirect Branch Predictor (IBP) and Branch Target Buffer (BTB) on Intel Alder Lake and Raptor Lake CPUs to induce speculative execution and exfiltrate data via cache side channels; researchers published full technical details and proof-of-concept tools and recommend mitigations such as more aggressive IBPB use and redesigned BPU tagging/randomization, though these carry substantial performance costs.
