Echo: linux: security update to 6.1.135-1

medium Tenable Self-Hosted Container Security Plugin ID 458463

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: netlabel: Fix NULL pointer exception
 caused by CALIPSO on IPv4 sockets When calling netlbl_conn_setattr(), addr->sa_family is used to determine
 the function behavior. If sk is an IPv4 socket, but the connect function is called with an IPv6 address,
 the function calipso_sock_setattr() is triggered. Inside this function, the following code is executed:
 sk_fullsock(__sk) ? inet_sk(__sk)->pinet6 : NULL; Since sk is an IPv4 socket, pinet6 is NULL, leading to a
 null pointer dereference. This patch fixes the issue by checking if inet6_sk(sk) returns a NULL pointer
 before accessing pinet6. (CVE-2025-22063)

Solution

Update the linux library and its related packages to version 6.1.135-1 or later.
