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.

Fix this by initializing oct->props[i].netdev before calling the queue

CVE-2026-23258 [MEDIUM] CVE-2026-23258 kernel: net: liquidio: Initialize netdev pointer before queue setup
CVE-2026-23258 kernel: net: liquidio: Initialize netdev pointer before queue setup
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
