What to do
AI-suggested
A fix has been implemented in the Linux kernel to add the required NULL check. Users should update to the fixed kernel version once available. No other mitigation actions are indicated.
Description
A NULL pointer dereference vulnerability was identified and fixed in the Linux kernel's ice driver. The function ice_lag_is_switchdev_running() was called outside its expected context, leading to a possible NULL dereference of lag->upper_netdev. This could cause a denial of service due to kernel crash or instability.
