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，已修复以下漏洞： net: hisilicon: hisi_femac：调整 netdev_ops 的赋值顺序以修复崩溃问题 函数在将 赋值之前，就先连接了 PHY 设备。自相关提交后， 会调用 ，而该函数会通过 读取 。因此，当启用了 配置项时，探测过程会因空指针解引用而引发崩溃。 崩溃调用栈如下： 修复方案：在连接 PHY 之前先赋值 ，这与提交 7c9f391ec89c（"net: emac: move setting of netops to fix crash"）中针对 驱动所采用

Vulnerability Title
net: hisilicon: hisi_femac: 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: hisi_femac: Move setting of netops to fix crash hisi_femac_drv_probe() connects the PHY before dev->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. phy_link_topo_add_phy from phy_attach_direct+0xec/0x37c of_phy_get_and_connect from hisi_femac_drv_probe+0x1f4/0x558 Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b Assign netdev_ops before the PHY attach, as was done for emac in commit 7c9f391ec89c ("net: emac: move setting of netops to fix crash").
