From 3315e716999d98d628abebbffaa82bef52962c95 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 30 Nov 2021 13:51:17 +0300 Subject: [PATCH] hwmon: (asus_wmi_sensors) fix an array overflow 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.
