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.
