However, network drivers can attach and detach PHY devices prior to net_device registration (such as during USB probe in asix/usbnet before register_netdev()), where RTNL is not held. When phylink_connect_phy() fails bringup and rolls back via phy_detach(), the absence of RTNL triggers a suspicious RCU usage warning. In a production kernel without lockdep, the pointer dereference proceeds safely and no memory corruption, leak, or denial of service occurs. full analysis:
