"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: liquidio: Initialize netdev pointer before queue setup\n\nIn setup_nic_devices(), the netdev is allocated using alloc_etherdev_mq().\nHowever, the pointer to this structure is stored in oct->props[i].netdev\nonly after the calls to netif_set_real_num_rx_queues() and\nnetif_set_real_num_tx_queues().\n\nIf either of these functions fails, setup_nic_devices() returns an error\nwithout freeing the allocated netdev. Since oct->props[i].netdev is still\nNULL at this point, the cleanup function liquidio_destroy_nic_device()\nwill fail to find and free the netdev, resulting in a memory leak.\n\nFix this by initializing oct->props[i].netdev before calling the queue\nsetup functions. This ensures that the netdev is properly accessible for\ncleanup in case of errors.\n\nCompile tested only. Issue found using a prototype static analysis tool\nand code review."
