Chipzilla's silicon will surrender secrets if properly probed
Computer security researchers involved in the discovery of the Meltdown and Spectre vulnerabilities affecting many modern processors have developed a related attack technique called Load Value Injection (LVI).
The attack relies on microarchitectural data leakage to inject and execute malicious code in a way that breaks the confidentiality of modern Intel systems.
Chipzilla's processors, already weighed down by defenses deployed against side-channel attacks over the past two years, could get slower still if they try to thwart this latest vulnerability: prototype compiler changes, for full mitigation, have produced performance reductions ranging from 2x to 19x.
That's because LVI protection involves compiler and assembler updates that insert extra ..
