Technical details
The nvmet-rdma driver fails to deallocate queue and IB resources in the error path when pending disconnecting queues exceed the backlog limit; it only drops the device reference. A remote attacker with network access to the RDMA service can repeatedly trigger connection attempts that exceed the backlog, causing accumulated resource leaks and eventual denial of service.
