[Small Typo] Display Issue with `W\^X` on Mitigations Page

[pufanyi]

Hello,

Thanks so much for the great textbook!

I noticed a small display issue on the mitigations page of the CS161 textbook. The text W\^X does not render correctly in the browser; it appears to be a typo or formatting error.

https://github.com/cs161-staff/textbook/blob/1e30910875229d77212d85b43f470998f0334ea3/memory-safety/mitigations.md?plain=1#L41

Here is how it looks in my browser (link here):

It might be more appropriate to change it to W^X for the correct display.

Thank you!
