  "title": "net: ethernet: mtk_eth_soc: unregister net_devices in case of probe failure",
  "description": "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-\u003Ereg_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.",
