Thanks’ for the reply, updated to latest kernel ( 4.14.14 ) still shows vulnerable to ‘ Spectre Variant 1 and 2 ‘ , any thoughts would be appreciated, maybe try some older versions ?

@Richard

This means that your system is vulnerable to ‘ Spectre Variant 1 and 2 ‘. Therefore try to update your kernel to one which has a patch for the flaws.

Check out this guide: https://www.tecmint.com/upgrade-kernel-in-ubuntu/ or update your kernel as follows:

$sudo apt update
$sudo apt-cache search linux-image
$sudo apt install – -only-upgrade
