Deskripsi (NVD)

In the Linux kernel, the following vulnerability has been resolved: net: liquidio: Initialize netdev pointer before queue setup In setup_nic_devices(), the netdev is allocated using alloc_etherdev_mq(). However, the pointer to this structure is stored in oct->props[i].netdev only after the calls to netif_set_real_num_rx_queues() and netif_set_real_num_tx_queues(). If either of these functions fails, setup_nic_devices() returns an error without freeing the allocated netdev. Since oct->props[i].netdev is still NULL at this point, the cleanup function liquidio_destroy_nic_device() will fail to find and free the netdev, resulting in a memory leak. Fix this by initializing oct->props[i].netdev before calling the queue setup functions. This ensures that the netdev is properly accessible for cleanup in case of errors. Compile tested only. Issue found using a prototype static analysis tool and code review.
