https://yanglingxi1993.github.io/dirty_pagetable/dirty_pagetable.html has been updated with exploit information. I tried to backtrack through kernel git to find the exact commit where this locking problem got fixed, but I gave up after a while after multiple refactoring (and a filemove) in the io_uring codel.
I guess it's this: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-5.15.y&id=fb348857e7b67eefe365052f1423427b66dedbf3 as mentioned in: https://twitter.com/VAR10CK/status/1683303642173153280 Alexander
