"Intel, AMD CPUs on Linux Impacted by Newly Disclosed Spectre Bypass"
The latest generations of Intel processors and AMD's older microarchitectures on Linux are vulnerable to new speculative execution attacks capable of bypassing current "Spectre" mitigations. The new attacks disclosed by ETH Zurich researchers undermine the Indirect Branch Predictor Barrier (IBPB) on x86 processors, which is a critical defense mechanism against speculative execution attacks. This article continues to discuss the new speculative execution attacks that bypass existing Spectre mitigations.
