CVE-2026-99198— net: ethernet: actions: 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: ethernet: actions：将 netops 的赋值操作提前，以修复崩溃问题。函数在将赋值之前，就会调用来连接 PHY。自相关提交之后，会调用，后者通过读取。因此，当启用配置选项时，探测过程会因空指针解引用而崩溃。解决方法是：在连接 PHY 之前先赋值，这与 commit 7c9f391ec89c（"net: emac: move setting of netops to fix crash"）中对 emac 驱动所做的修复一致。

Vulnerability Title

net: ethernet: actions: 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: 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").
