In the Linux kernel, the following vulnerability has been resolved:ksmbd: call rcu_barrier() in ksmbd_server_exit()racy issue is triggered the bug by racing between closing a connectionand rmmod. In ksmbd, rcu_barrier() is not called at module unload time,so nothing prevents ksmbd from getting unloaded while it still has RCUcallbacks pending.
