Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
nvme: fix admin request_queue lifetime<br />
<br />
The namespaces can access the controller&#39;s admin request_queue, and<br />
stale references on the namespaces may exist after tearing down the<br />
controller. Ensure the admin request_queue is active by moving the<br />
controller&#39;s &#39;put&#39; to after all controller references have been released<br />
to ensure no one is can access the request_queue. This fixes a reported<br />
use-after-free bug:<br />
<br />
