I think people would like to understand what the "sandbox" is here and what isolation does it provide, is it an unprivileged process? something chromium specific? a v8/JS thing? etc.

Seems to use OS-specific kernel syscall filtering facilities.

V8 also has its own sandbox, which I believe exists in that sandbox. I assume that's the one this exploit has RCE in, but its unclear.

I would assume in this case that there's full renderer control, not just a bypass of the in-process isolation.
