CVE-2026-98112

HIGH

Description

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.
