What it is

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.
