New Research Reveals Spectre Vulnerability Persists in Latest AMD and Intel Processors

More than six years after the Spectre security flaw impacting modern CPU processors came to light, new research has found that the latest AMD and Intel processors are still susceptible to speculative execution attacks.

The attack, disclosed by ETH Zürich researchers Johannes Wikner and Kaveh Razavi, aims to undermine the Indirect Branch Predictor Barrier (IBPB) on x86 chips, a crucial mitigation against speculative execution attacks.

Speculative execution refers to a performance optimization feature wherein modern CPUs execute certain instructions out-of-order by predicting the branch a program will take beforehand, thus speeding up the task if the speculatively used value was correct.

"Intel users should make sure their intel-microcode is up to date," the researchers said. "AMD users should make sure to install kernel updates."
