Meltdown and Specter issues.
 

I am running Intel(R) Core(TM)2 Duo CPU E8600 @ 3.33GHz in my desktop how do I update driver in Linux mint 18.3 or do I need too for security reasons? Due to latest threats out there.Please advise. I can send a screen shot of CPU if necessary. Thanks in advance.

You need to update your kernel. Check in the Linux-Mint forum for the proper updated kernel because they are not all the same for all Linux distros. Or you can ask Joe Collins here https://www.youtube.com/user/BadEdit...able_polymer=1

please paste output of

4.10.0-38-generic #42~16.04.1-Ubuntu SMP Tue Oct 10 16:32:20 UTC 2017

Updated kernel to 4.13.06 hope that is what I was supposed to do. Desktop seems to be working ok.
4.13.6-041306-generic #201711060046 SMP Mon Nov 6 00:47:15 UTC 2017

update
 

just do an update, which I assume we all do regularly.
This should update the kernel and maybe a few other apps.
I read there were some 'features' in the security update locking up some servers.

Thanks for your help.

Please see https://blog.linuxmint.com/?p=3496 for info on steps to take in order to combat the Meltdown and Spectre threats, and refer to the Mint blog from time to time in future to keep an eye out for updated details.

The latest kernel is currently 4.13.0-31. Use View->Linux kernels in Mint's Update Manager to see which kernels are available and to install the latest one.

i'm sorry, i assumed that the architecture would be visible from that output (it is on my system).
so in addition, to that, if it's 32bit (usually i686 i guess), you might NOT be protected against meltdown, even with the latest kernel.
if it's ARM, you are not vulnerable.
if it IS 64bit, you should make sure you have one of the kernel versions that are patched.
