Echo: linux: security update to 6.1.159-1

critical Tenable Cloud Security Plugin ID 464886

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: nvmet-fc: avoid scheduling association
 deletion twice When forcefully shutting down a port via the configfs interface,
 nvmet_port_subsys_drop_link() first calls nvmet_port_del_ctrls() and then nvmet_disable_port(). Both
 functions will eventually schedule all remaining associations for deletion. The current implementation
 checks whether an association is about to be removed, but only after the work item has already been
 scheduled. As a result, it is possible for the first scheduled work item to free all resources, and then
 for the same work item to be scheduled again for deletion. Because the association list is an RCU list, it
 is not possible to take a lock and remove the list entry directly, so it cannot be looked up again.
 Instead, a flag (terminating) must be used to determine whether the association is already in the process
 of being deleted. (CVE-2025-40343)

Solution

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