Echo: linux: security update to 6.1.162-1

high Tenable Cloud Security Plugin ID 458571

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: netrom: fix double-free in
 nr_route_frame() In nr_route_frame(), old_skb is immediately freed without checking if nr_neigh->ax25
 pointer is NULL. Therefore, if nr_neigh->ax25 is NULL, the caller function will free old_skb again,
 causing a double-free bug. Therefore, to prevent this, we need to modify it to check whether
 nr_neigh->ax25 is NULL before freeing old_skb. (CVE-2026-23098)

Solution

Update the linux library and its related packages to version 6.1.162-1 or later.
