Echo: linux: security update to 6.1.176-1

medium Tenable Cloud Security Plugin ID 455233

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: v: stop OGMv2 on disabled
 interface When a batadv_hard_iface is disabled, its mesh_iface pointer is set to NULL. However,
 batadv_v_ogm_send_meshif() may still dispatch OGMs via batadv_v_ogm_queue_on_if() for interfaces that have
 since lost their mesh_iface association. This results in a NULL pointer dereference when
 batadv_v_ogm_queue_on_if() unconditionally calls netdev_priv() on the now NULL hard_iface->mesh_iface to
 retrieve the batadv_priv. It is necessary to ensure that the batadv_v_ogm_queue_on_if() checks that it is
 using the same mesh_iface for which batadv_v_ogm_send_meshif() was called. (CVE-2026-52913)

Solution

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