Echo: linux: security update to 6.1.148-1

medium Tenable Cloud Security Plugin ID 462575

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: ipv6: prevent infinite loop in
 rt6_nlmsg_size() While testing prior patch, I was able to trigger an infinite loop in rt6_nlmsg_size() in
 the following place: list_for_each_entry_rcu(sibling, &f6i->fib6_siblings, fib6_siblings) {
 rt6_nh_nlmsg_size(sibling->fib6_nh, &nexthop_len); } This is because fib6_del_route() and
 fib6_add_rt2node() uses list_del_rcu(), which can confuse rcu readers, because they might no longer see
 the head of the list. Restart the loop if f6i->fib6_nsiblings is zero. (CVE-2025-38588)

Solution

Update the linux library and its related packages to version 6.1.148-1 or later.
