My macbook just had a CPU related error?

So I was just chilling in Reddit and my MacBook Pro (2017 13" Base Model) completely froze for about 10seconds. I panicked and then the macbook just restarted by himself. So when i log in, i get the message "Your macbook just restarted because of a problem" and the crash message says this:

Can someone tell me what happened? The macbook is still in warranty since i'm Europe and i've had it for about a year and a half now, but I would really like to hope that this is not a hardware problem and that it won't happen again.

Thanks
