Описание
In the Linux kernel, the following vulnerability has been resolved:
nvme: target: rdma: fix ndev refcount leak on queue connect
nvmet_rdma_queue_connect() calls nvmet_rdma_find_get_device() which acquires a reference on the returned ndev via kref_get(). On the path where the host queue backlog is exceeded and the function returns NVME_SC_CONNECT_CTRL_BUSY, reference of ndev is not released, leaking the kref.
Fix this by adding a goto to the existing put_device label before the early return.

A flaw was found in the NVMe over RDMA (nvmet_rdma) target in the Linux kernel. When a host queue backlog is exceeded during a connection attempt, a reference count (kref) is not properly released. This oversight can lead to a resource exhaustion vulnerability, potentially allowing a remote attacker to cause a Denial of Service (DoS) by depleting system resources.
