UBUNTU-CVE-2026-98112: High severity ubuntu/linux-hwe-edge vulnerability

In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix listener task lifetime on netdev events The listener thread exits when its listening socket is shutdown. The netdevice notifier shuts down the socket before calling kthreadstop(), so the taskstruct can be freed before kthreadstop() gets its reference. Create the listener in a stopped state and hold an extra taskstruct reference until kthreadstopput() completes. Also stop and release listeners before freeing their interface records during TCP teardown.
