CVE-2026-64321

nvme: target: rdma: fix ndev refcount leak on queue connect

State: Published
Severity: Not scored

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.
