Echo: linux: security update to 6.1.162-1

medium Tenable Cloud Security Plugin ID 459065

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: can: j1939: make
 j1939_session_activate() fail if device is no longer registered syzbot is still reporting
 unregister_netdevice: waiting for vcan0 to become free. Usage count = 2 even after commit 93a27b5891b8
 ("can: j1939: add missing calls in NETDEV_UNREGISTER notification handler") was added. A debug printk()
 patch found that j1939_session_activate() can succeed even after j1939_cancel_active_session() from
 j1939_netdev_notify(NETDEV_UNREGISTER) has completed. Since j1939_cancel_active_session() is processed
 with the session list lock held, checking ndev->reg_state in j1939_session_activate() with the session
 list lock held can reliably close the race window. (CVE-2025-71182)

Solution

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