CVE-2026-64321
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().
Does this matter?
Lower severity and a low EPSS score (0.12%). Track it; it rarely justifies an emergency change on its own.
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.
