Live › vulnerability › CVE-2026-99199
Go to dashboardIn the Linux kernel's hip04_eth network driver for HiSilicon hardware, the probe path attaches the PHY before setting netdev_ops, so a NULL pointer dereference occurs when CONFIG_NET_SHAPER is enabled. The sources describe a crash during driver probe, not code execution or data theft.
Summary written from the sources below. Check the originals before acting.

Only systems running the Linux kernel with the hip04_eth driver (HiSilicon hip04 Ethernet hardware, typically older ARM server or set-top boards) and CONFIG_NET_SHAPER enabled are exposed to the probe crash. Teams on x86 servers, cloud VMs or other NIC drivers can skip it.

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").
