A microcode program that is executed by the processor during the microcode update process. [1] This microcode is able to reconfigure and enable or disable components using a special register, and it must update the breakpoint match registers. [1] Up to sixty patched micro-operations to be populated into the SRAM. [1] Padding consisting of ...
The Intel Management Engine (ME), also known as the Intel Manageability Engine, [1] [2] is an autonomous subsystem that has been incorporated in virtually all of Intel's processor chipsets since 2008. [1] [3] [4] It is located in the Platform Controller Hub of modern Intel motherboards.
Intel promised microcode updates to resolve the vulnerability. [1] The microcode patches have been shown to significantly reduce the performance of some heavily-vectorized loads. [7] Patches to mitigate the effects of the vulnerability have also been created as part of the forthcoming version 6.5 release of the Linux kernel. [8]
Windows 10 is a version of Windows NT and the successor of Windows 8.1. Some features of the operating system were removed in comparison to Windows 8 and Windows 8.1, and further changes in features offered have occurred within subsequent feature updates to Windows 10. Following is a list of these.

Meltdown exploits a race condition, inherent in the design of many modern CPUs.This occurs between memory access and privilege checking during instruction processing. . Additionally, combined with a cache side-channel attack, this vulnerability allows a process to bypass the normal privilege checks that isolate the exploit process from accessing data belonging to the operating system and other ...
Intel reported that they are preparing new patches to mitigate these flaws. [24] On August 14, 2018, Intel disclosed three additional chip flaws referred to as L1 Terminal Fault (L1TF). They reported that previously released microcode updates, along with new, pre-release microcode updates can be used to mitigate these flaws. [25] [26]
Some hardware vendors, notably IBM and Lenovo, use the term microcode interchangeably with firmware. In this context, all code within a device is termed microcode, whether it is microcode or machine code. For instance, updates to a hard disk drive's microcode often encompass updates to both its microcode and firmware. [3]
