## Overview

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 io_kiocb, 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 io_kiocb
for the vectored buffer import.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
