Summary
In the Linux kernel, the following vulnerability has been resolved:
io_uring/waitid: always prune wait queue entry in io_waitid_wait()
For a successful return, always remove our entry from the wait queue entry list. Previously this was skipped if a cancelation was in progress, but this can race with another invocation of the wait queue entry callback.
