Cpuinfo showing something worrisome [Solved]

My laptop CPU kept overheating if I opened too many tabs, so I decided to cat /proc/cpuinfo and found this line (someone should pin a god damn topic how to markdown code)

bugs        : cpu_meltdown spectre_v1 spectre_v2 spec_store_bypass l1tf mds swapgs itlb_multihit

From little a found I can only assume this is a bad thing, but I can't find anything about it being more than a vulnerability. Any ideas how to deal with this and maybe fix the overheating problem (if it's on CPU side)?

Full output of cat /proc/cpuinfo: https://pastebin.com/gCukMRxg

Edit: Thanks for the help

Re: Cpuinfo showing something worrisome [Solved]

This is a list of known hardware bugs/vulnerabilities of that particular CPU.
This is unlikely to have anything to do with your overheating problem.
To mitigate Meltdown and Spectre, you should use an up-to-date kernel with the Retpoline feature and up-to-date Microcode for your particular CPU.

To check if you are, or are not, vulnerable to the spectre/meltdown vulnerabilities on a particular system you can run the script (as root) from from the site at https://github.com/speed47/spectre-meltdown-checker and is updated as new vulnerabilities of that type become known, but as has been said it is not likely connected to a cpu overheating.

Start by checking if the CPU fan is working.
