Echo: linux: security update to 6.1.170-1

high Tenable Cloud Security Plugin ID 457359

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: openvswitch: defer tunnel netdev_put
 to RCU release ovs_netdev_tunnel_destroy() may run after NETDEV_UNREGISTER already detached the device.
 Dropping the netdev reference in destroy can race with concurrent readers that still observe vport->dev.
 Do not release vport->dev in ovs_netdev_tunnel_destroy(). Instead, let vport_netdev_free() drop the
 reference from the RCU callback, matching the non-tunnel destroy path and avoiding additional
 synchronization under RTNL. (CVE-2026-31678)

Solution

Update the linux library and its related packages to version 6.1.170-1 or later.
