io-uring is a security nightmare. Constant privescs and a powerful primitive for syscall smuggling. Worth considering disabling it outright (already the case for most containers afaik).

At one point, Google disabled io_uring on its production servers (https://security.googleblog.com/2023/06/learnings-from-kctf-...) - I don't know whether this is still true, though. Perhaps a Google can confirm.
super curious on this one as well, last I heard they've been enabling it slowly
