Echo: linux: security update to 6.1.176-1

high Tenable Self-Hosted Container Security Plugin ID 465632

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-46208)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
