AI-suggested
A fix is available that moves the assignment of netdev_ops to before the PHY attachment in the hisilicon femac driver. Users should apply the updated Linux kernel patch that addresses this issue. No other mitigation steps are indicated.
Description
A vulnerability in the Linux kernel's hisilicon femac driver causes a crash due to a NULL pointer dereference during device probing when CONFIG_NET_SHAPER is enabled. The issue arises because the network device operations (netdev_ops) are assigned after the PHY connection attempt, leading to a kernel panic. The fix involves assigning netdev_ops before attaching the PHY.
