Description

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: actions: Move setting of netops to fix crash owl_emac_probe() calls owl_emac_phy_init(), which connects the PHY, before netdev->netdev_ops is assigned. phy_attach_direct() -> phy_link_topo_add_phy() reads dev->netdev_ops through netdev_need_ops_lock() since the commit in question, so probing crashes with a NULL pointer dereference when CONFIG_NET_SHAPER is enabled. Assign netdev_ops before the PHY attach, as was done for emac in commit 7c9f391ec89c ("net: emac: move setting of netops to fix crash").
