CVE-2026-46208 Details
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.
A vulnerability exists in the Linux kernel's batman-adv module, specifically related to the management of throughput (TP) meter sessions during the teardown of mesh interfaces. When a mesh interface is removed, the current process does not first clear active TP meter sessions, which can lead to issues. This oversight allows a sending thread or a delayed TP meter packet to continue processing with a mesh instance that is already in the process of shutting down. The vulnerability affects several versions of the Linux kernel.
The vulnerability has been addressed in the Linux kernel. Users should upgrade to the latest version where this issue has been fixed.
