In the wake of these events, vendors who rely on this hardware have had to likewise scramble to issue mitigations for their products. microcode updates).ĭue to the serious nature of these flaws, chip developers such as Intel, AMD, and ARM have had to issue an emergency press conference releases, and Intel has further promised to deliver “ Firmware Updates for Most Modern CPUs by the End of Next Week.” Furthermore, for performance reasons, speculative execution is almost always implemented in hardware, so “fixes” tend toward mitigations (e.g. Since this is an important feature and not a bug, it is inherently hard to fix. These flaws root in two critical CPU features: Out of Order Execution and Speculative Execution, which are crucial for performance. ![]() 2018 truly is starting off with a bang: fundamental CPU flaws dubbed Meltdown and Spectre were found affecting pretty much all modern processors developed since the Pentium Pro (1995).
