New Exploit Bypasses Existing Spectre-v2 Mitigations in Intel, AMD, Arm CPUs

Researchers have disclosed a new technique that could be used to circumvent existing hardware mitigations in modern processors from Intel, AMD, and Arm and stage speculative execution attacks such as Spectre to leak sensitive information from host memory. Attacks like Spectre are designed to break the isolation between different applications by taking advantage of an optimization technique
