Summary
io_uring/net: ensure vectored buffer node import is tied to notification
Details

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

io_uring/net: ensure vectored buffer node import is tied to notification

When support for vectored registered buffers was added, the import itself is using 'req' rather than the notification iokiocb, sr->notif. For non-vectored imports, sr->notif is correctly used. This is important as the lifetime of the two may be different. Use the correct iokiocb for the vectored buffer import.
