  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: ethernet: mtk_eth_soc: unregister net_devices in case of probe failure\n\nIf register_netdev() fails for one of the MTK_MAX_DEVS devices in\nmtk_probe(), the error path jumps to err_deinit_ppe, skipping\nmtk_unreg_dev(). The previously registered net_devices are then freed by\nmtk_free_dev() while still in NETREG_REGISTERED state, hitting the\nBUG_ON(dev->reg_state != NETREG_UNREGISTERED).\n\nRoute the register_netdev() failure to err_unreg_netdev so the net_devices\nregistered so far are properly unregistered before being freed.",
