Intel has released a document that explains which CPUs will not receive a Spectre / Meltdown patch. Chipzilla believes that these CPUs are typically implemented in closed systems and are expected to have a lower likelihood of exposure to vulnerabilities. Also it was deemed not practical to patch some CPUs. Stopped – After a comprehensive investigation of the microarchitectures and microcode capabilities for these products, Intel has determined to not release microcode updates for these products for one or more reasons including, but not limited to the following: • Micro-architectural characteristics that preclude a practical implementation of features mitigating Variant 2 (CVE-2017-5715) • Limited Commercially Available System Software support • Based on customer inputs, most of these products are implemented as “closed systems” and therefore are expected to have a lower likelihood of exposure to these vulnerabilities A lot of our readership purchases old servers through the resale market for projects. So on one hand I would like to see everything properly patched, but if something is truly ancient then what's the point?
