Echo: linux: security update to 6.1.170-1

high Tenable Self-Hosted Container Security Plugin ID 462042

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: wifi: virt_wifi: remove SET_NETDEV_DEV
 to avoid use-after-free Currently we execute `SET_NETDEV_DEV(dev, &priv->lowerdev->dev)` for the virt_wifi
 net devices. However, unregistering a virt_wifi device in netdev_run_todo() can happen together with the
 device referenced by SET_NETDEV_DEV(). It can result in use-after-free during the ethtool operations
 performed on a virt_wifi device that is currently being unregistered. Such a net device can have the
 `dev.parent` field pointing to the freed memory, but ethnl_ops_begin() calls
 `pm_runtime_get_sync(dev->dev.parent)`. Let's remove SET_NETDEV_DEV for virt_wifi to avoid bugs like this:
