Summary
In the Linux kernel, the following vulnerability has been resolved:
smb: server: split ksmbd_rdma_stop_listening() out of ksmbd_rdma_destroy()
We can't call destroy_workqueue(smb_direct_wq); before stop_sessions()!
Otherwise already existing connections try to use smb_direct_wq as
a NULL pointer.
