Thanks for the correction; my knowledge is a bit out of date, Firefox at least (not sure about Safari) switched to W^X JIT a good while back: https://jandemooij

Thanks for the correction; my knowledge is a bit out of date, Firefox at least (not sure about Safari) switched to W^X JIT a good while back: https://jandemooij.nl/blog/wx-jit-code-enabled-in-firefox/ https://jandemooij.nl/blog/wx-jit-code-enabled-in-firefox/. That's cool. W^X is more difficult to exploit for sure, but as other commenters point out, unfortunately still possible.
