Intel Releases Processor Microcode Patch for Linux OSes, Here's How to Update
"Here's how to update the Intel CPU microcode on Linux"
The archive released by Intel for Linux OSes contains a microcode.dat file, which is available in a traditional text format and still used in some Linux distros, allowing users to update the Intel CPU microcode through the old microcode update interface that's available in the Linux kernel with and can be enabled with the CONFIG_MICROCODE_OLD_INTERFACE=y option.
To update the microcode.dat to the system, you will need to first ensure the existence of /dev/cpu/microcode and then write microcode.dat to the file with the dd if=microcode.dat of=/dev/cpu/microcode bs=1M command in a terminal emulator. Once the writing process is complete, you will have to reboot your computer for any changes to take effect.
The updated microcode archive also contains an intel-ucode folder, which is the second method of installing the microcode, supported by most modern GNU/Linux distributions. To update this way, ensure the existence of /sys/devices/system/cpu/microcode/reload, copy the entire intel-ucode directory to /lib/firmware, overwrite the files in /lib/firmware/intel-ucode/, write the reload interface to 1 to reload the microcode files (e.g. echo 1 > /sys/devices/system/cpu/microcode/reload), and reboot.
