Doc Text:
A vulnerability was found in the netdev_trig_notify() function in the Linux Kernel's led ledtrig-netdev.c driver, where a call to the get_device_state() function may lead to a kernel panic. This can occur when the interface is renamed, because the function get_device_state() still uses the old device reference found in trigger_data, which may not have been updated to the new device, resulting in an invalid memory reference. This issue can lead to system instability.
