Pavel Skripkin e3a5de6d81 net: ethernet: aeroflex: fix UAF in greth_of_remove ... static int greth_of_remove(struct platform_device *of_dev) { ... struct greth_private *greth = netdev_priv(ndev); ... unregister_netdev(ndev); free_netdev(ndev); of_iounmap(&of_dev->resource[0], greth->regs, resource_size(&of_dev->resource[0])); ... } greth is netdev private data, but it is used after free_netdev(). It can cause use-after-free when accessing greth pointer. So, fix it by moving free_netdev() after of_iounmap() call.
