Subject description: a shell script to be used as root

spectre-meltdown-checker is a simple shell script to check if your Linux system is vulnerable against the 3 “speculative execution” CVEs (Common Vulnerabilities and Exposures) that were made public early this year. Once you run it, it will inspect your currently running kernel.

$ git clone https://github.com/speed47/spectre-meltdown-checker.git
$ cd spectre-meltdown-checker/
$ sudo ./spectre-meltdown-checker.sh

Hi labbe5.

Have you tried this script on your machine? Did it work?

I have read that applying such patches may turn your computer into a "brick" or a
"doorstop" if your CPU is an AMD CPU and not an Intel CPU.

Given the above, I'm not absolutely sure I should thank you for this reference! Wink

BFN.
