Description

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-&gt;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.
