Intel must update all microcodes or release the old source code of discontinued products !

[theLOICofFRANCE]

Hello,

If you do not replace all the vulnerable processors you have marketed for many years, please update all the microcodes of the discontinued products or give us the source code to correct your work.

Thank you...

Example of a vulnerable product that you didn't take the time to fix:

dmesg

[    0.000000] microcode: microcode updated early to revision 0xa4, date = 2010-10-02

Given the number of vulnerabilities in your products and the drop in performance with each of your patches, I think that a class action suit against you will be the only thing that will open your mind...

Please, release the source code of the microcode if the product has not been marketed for example for 5 years.

Thank you
