CVE-2026-99199— net: hisilicon: hip04_eth: Move setting of netops to fix crash

Quick assessment

Affected

Linux Linux

Exploitation

No confirmed in-the-wild exploitation; assess based on exposure

Recommended action

Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，以下漏洞已得到修复： net: hisilicon: hip04_eth：将 netops 的赋值操作提前以修复崩溃问题函数在被赋值之前，就调用了。自相关提交后，会调用，而后者会通过读取。因此，当启用配置时，探测过程会因空指针解引用而引发崩溃。修复方法是将的赋值操作提前到 PHY 连接之前，这与提交 7c9f391ec89c（"net: emac: move setting of netops to fix crash"）中针对 emac 驱动所做的处理一致。

Vulnerability Title

net: hisilicon: hip04_eth: Move setting of netops to fix crash

Source: CVE Program / CVE List V5

Vulnerability Description

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").
