7.8 HIGH — CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Description

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

Affected configurations

• linux linux kernel (>= 4.8 < 6.6.140) • linux linux kernel (>= 6.7 < 6.12.90) • linux linux kernel (>= 6.13 < 6.18.32) • linux linux kernel (>= 6.19 < 7.0.9) • linux linux kernel 7.1
