    Several years ago, Google engineers began developing the Address Space Isolation (ASI) mechanism for the Linux kernel, designed to shield systems from attacks exploiting speculative processor execution. The aim was to create a universal safeguard rather than crafting individual patches for each newly discovered vulnerability. However, the initial iteration of ASI proved virtually unusable due…
