Echo: linux: security update to 6.1.147-1

medium Tenable Self-Hosted Container Security Plugin ID 462243

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: net: Fix TOCTOU issue in
 sk_is_readable() sk->sk_prot->sock_is_readable is a valid function pointer when sk resides in a sockmap.
 After the last sk_psock_put() (which usually happens when socket is removed from sockmap), sk->sk_prot
 gets restored and sk->sk_prot->sock_is_readable becomes NULL. This makes sk_is_readable() racy, if the
 value of sk->sk_prot is reloaded after the initial check. Which in turn may lead to a null pointer
 dereference. Ensure the function pointer does not turn NULL after the check. (CVE-2025-38112)

Solution

Update the linux library and its related packages to version 6.1.147-1 or later.
