Description
In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: fix potential use-after-free in ec_bhf_remove
static void ec_bhf_remove(struct pci_dev *dev) { ... struct ec_bhf_priv *priv = netdev_priv(net_dev);
unregister_netdev(net_dev); free_netdev(net_dev);
pci_iounmap(dev, priv->dma_io); pci_iounmap(dev, priv->io); ... }
priv is netdev private data, but it is used after free_netdev(). It can cause use-after-free when accessing priv pointer. So, fix it by moving free_netdev() after pci_iounmap() calls.
