Meltdown The Sequel strikes Intel chips – and full mitigation against data-meddling LVI flaw will slash performance
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.
