In the Linux kernel, the following vulnerability has been resolved:
smb: server: fix leak of active_num_conn in ksmbd_tcp_new_connection()
On kthread_run() failure in ksmbd_tcp_new_connection(), the transport is
freed via free_transport(), which does not decrement active_num_conn,
leaking this counter.
Replace free_transport() with ksmbd_tcp_disconnect().
