CVE-2026-99199 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: net: hisilicon: hip04_eth: Move setting of netops to fix crash hip04_mac_probe() calls of_phy_connect() before ndev->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")..
