batman-adv: stop tp_meter sessions during mesh teardown_CVE-2026-46208

{
    "lastseen": "",
    "description": "In the Linux kernel, the following vulnerability has been resolved:\n\nbatman-adv: stop tp_meter sessions during mesh teardown\n\nTP meter sessions remain linked on bat_priv->tp_list after the netlink\nrequest has already finished. When the mesh interface is removed,\nbatadv_mesh_free() currently tears down the mesh without first draining\nthese sessions.\n\nA running sender thread or a late incoming tp_meter packet can then keep\nprocessing against a mesh instance which is already shutting down.\nSynchronize tp_meter with the mesh lifetime by stopping all active\nsessions from batadv_mesh_free() and waiting for sender threads to exit\nbefore teardown continues.",
