In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: mtk_eth_soc: unregister net_devices in case of probe failure
If register_netdev() fails for one of the MTK_MAX_DEVS devices in
mtk_probe(), the error path jumps to err_deinit_ppe, skipping
mtk_unreg_dev(). The previously registered net_devices are then freed by
mtk_free_dev() while still in NETREG_REGISTERED state, hitting the
BUG_ON(dev->reg_state != NETREG_UNREGISTERED).
Route the register_netdev() failure to err_unreg_netdev so the net_devices
registered so far are properly unregistered before being freed.
