I'm worried about the intel hardware level meltdown hacking. Several days ago, I experienced my Ubuntu system malfunctioning from booting. It went to something like initramfs. I couldn't fix the issue so I changed the kernel to previous version, 4.10. (I'm using Ubuntu 16.04.) Then it succeeded to boot normally. However I'm now worried since I feel like I should use the newer version that had issue booting. What should I do? Where do I confirm which version kernel is safe?

I followed the link and went to the page where new kernel exists. Then why are there the lower versions like 4.4?? – Smile Jan 17 '18 at 10:41

Because of backporting. – vidarlo Jan 17 '18 at 10:43

There is an open source bash script which checks vulnerabilities of your kernel and tells if it is patched.
wget https://raw.githubusercontent.com/speed47/spectre-meltdown-checker/master/spectre-meltdown-checker.sh
sudo chmod +x spectre-meltdown-checker.sh
and run it with root privileges
sudo sh spectre-meltdown-checker.sh
