Microsoft has released Intel microcode updates for Windows 10 versions 1909 and 1903 to address four recently disclosed security threats, including Zombieload.
The microcode updates are the latest installment of Microsoft’s efforts to help distribute firmware updates on behalf of the chip maker, addressing a variety of attacks on the optimization process known as speculative execution process.
The updates address four microarchitectural data-sampling (MDS) attacks that can exploit store buffers (CVE-2018-12126 aka Fallout), load buffers (CVE-2018-12127), line-fill buffers (CVE-2018-12130, aka the Zombieload attack, or RIDL), and uncacheable memory (CVE-2019-11091).
