Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
io_uring/net: ensure vectored buffer node import is tied to notification<br />
<br />
When support for vectored registered buffers was added, the import<br />
itself is using &#39;req&#39; rather than the notification io_kiocb, sr->notif.<br />
For non-vectored imports, sr->notif is correctly used. This is important<br />
as the lifetime of the two may be different. Use the correct io_kiocb<br />
for the vectored buffer import.
