Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
batman-adv: stop tp_meter sessions during mesh teardown<br />
<br />
TP meter sessions remain linked on bat_priv->tp_list after the netlink<br />
request has already finished. When the mesh interface is removed,<br />
batadv_mesh_free() currently tears down the mesh without first draining<br />
these sessions.<br />
<br />
A running sender thread or a late incoming tp_meter packet can then keep<br />
processing against a mesh instance which is already shutting down.<br />
Synchronize tp_meter with the mesh lifetime by stopping all active<br />
sessions from batadv_mesh_free() and waiting for sender threads to exit<br />
before teardown continues.
