  "title": "net: cpsw_new: Fix potential unregister of netdev that has not been registered yet",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  net: cpsw_new: Fix potential unregister of netdev that has not been registered yet  If an error occurs during register_netdev() for the first MAC in cpsw_register_ports(), even though cpsw-\u003Eslaves[0].ndev is set to NULL, cpsw-\u003Eslaves[1].ndev would remain unchanged. This could later cause cpsw_unregister_ports() to attempt unregistering the second MAC. To address this, add a check for ndev-\u003Ereg_state before calling unregister_netdev(). With this change, setting cpsw-\u003Eslaves[i].ndev to NULL becomes unnecessary and can be removed accordingly.",
