Echo: linux: security update to 6.1.158-1

high Tenable Cloud Security Plugin ID 463699

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: octeontx2-pf: Fix potential use after
 free in otx2_tc_add_flow() This code calls kfree_rcu(new_node, rcu) and then dereferences "new_node" and
 then dereferences it on the next line. Two lines later, we take a mutex so I don't think this is an RCU
 safe region. Re-order it to do the dereferences before queuing up the free. (CVE-2025-39978)

Solution

Update the linux library and its related packages to version 6.1.158-1 or later.
