CVE-2026-53321

In the Linux kernel, the following vulnerability has been resolved:

io_uring/napi: cap busy_poll_to 10 msec

Currently there's no cap on the maximum amount of time that napi is

allowed to poll if no events are found, which can lead to kernel

complaints on a task being stuck as there's no conditional rescheduling

done within that loop.

Just cap it to 10 msec in total, that's already way above any kind of

sane value that will reap any benefits, yet low enough that it's

nowhere near being able to trigger preemption complaints.
