  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: cpsw_new: Fix potential unregister of netdev that has not been registered yet\n\nIf an error occurs during register_netdev() for the first MAC in\ncpsw_register_ports(), even though cpsw->slaves[0].ndev is set to NULL,\ncpsw->slaves[1].ndev would remain unchanged. This could later cause\ncpsw_unregister_ports() to attempt unregistering the second MAC.\nTo address this, add a check for ndev->reg_state before calling\nunregister_netdev(). With this change, setting cpsw->slaves[i].ndev\nto NULL becomes unnecessary and can be removed accordingly.",
