Description
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.
Affected configurations
• linux linux kernel (>= 6.8 < 6.12.96)
• linux linux kernel (>= 6.13 < 6.18.39)
• linux linux kernel (>= 6.19 < 7.1.4)
