In the Linux kernel, the following vulnerability has been resolved: RDMA/ionic: Fix potential NULL pointer dereference in ionic_query_port The function ionic_query_port() calls ib_device_get_netdev() without checking the return value which could lead to NULL pointer dereference, Fix it by checking the return value and return -ENODEV if the 'ndev' is NULL.
