[PATCH 2/2] hwmon: (asus_wmi_sensors) fix an array overflow

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Smatch detects this array overflow:

    drivers/hwmon/asus_wmi_sensors.c:569 asus_wmi_configure_sensor_setup()
    error: buffer overflow 'hwmon_attributes' 8 <= 9

The hwmon_attributes[] array should have "hwmon_max" so that it gets
larger when more attributes are added.

Fixes: 9d07e54a25b8 ("hwmon: (asus_wmi_sensors) Support X370 Asus WMI.")
