CVE-2026-23258

In the Linux kernel, the following vulnerability has been resolved:

net: liquidio: Initialize netdev pointer before queue setup

In setupnicdevices(), the netdev is allocated using allocetherdevmq(). However, the pointer to this structure is stored in oct->props[i].netdev only after the calls to netifsetrealnumrxqueues() and netifsetrealnumtxqueues().

If either of these functions fails, setupnicdevices() returns an error without freeing the allocated netdev. Since oct->props[i].netdev is still NULL at this point, the cleanup function liquidiodestroynic_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.
