Echo: linux: security update to 6.1.159-1

medium Tenable Self-Hosted Container Security Plugin ID 462757

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: usbnet: Prevents free active kevent
 The root cause of this issue are: 1. When probing the usbnet device, executing usbnet_link_change(dev, 0,
 0); put the kevent work in global workqueue. However, the kevent has not yet been scheduled when the
 usbnet device is unregistered. Therefore, executing free_netdev() results in the "free active object
 (kevent)" error reported here. 2. Another factor is that when calling
 usbnet_disconnect()->unregister_netdev(), if the usbnet device is up, ndo_stop() is executed to cancel the
 kevent. However, because the device is not up, ndo_stop() is not executed. The solution to this problem is
 to cancel the kevent before executing free_netdev(). (CVE-2025-68312)

Solution

Update the linux library and its related packages to version 6.1.159-1 or later.
