CVE-2026-98112

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 kthread_stop(), so the task_struct can be freed before kthread_stop() gets its reference.

Create the listener in a stopped state and hold an extra task_struct reference until kthread_stop_put() completes. Also stop and release listeners before freeing their interface records during TCP teardown.
