Intel and AMD Chips Still Vulnerable to Spectre Flaw

Oct 29, 2024 | Over six years since the Spectre flaw was first revealed, Intel and AMD processors remain susceptible to speculative execution attacks. ETH Zurich researchers found these attacks exploit the Indirect Branch Predictor Barrier (IBPB) on x86 chips. While speculative execution boosts CPU performance, attackers can manipulate it to access unauthorized data, like encryption keys.

Intel issued a microcode patch (CVE-2023-38575), while AMD continues tracking its issue as CVE-2022-23824. John Gallagher from Viakoo Labs notes that speculative execution, present in all modern CPUs, enhances speed but comes with risks that are tough to patch.
