Subject: [PATCH AUTOSEL 4.19 15/19] hwmon: (scmi) Fix potential buffer overflow in scmi_hwmon_probe()
Date: Mon, 20 Jul 2020 17:38:46 -0400 [thread overview]
Message-ID: <20200720213851.407715-15-sashal@kernel.org> (raw)
In-Reply-To: <20200720213851.407715-1-sashal@kernel.org>
From: Cristian Marussi <cristian.marussi@arm.com>
[ Upstream commit 3ce17cd2b94907f6d91b81b32848044b84c97606 ]
SMATCH detected a potential buffer overflow in the manipulation of
hwmon_attributes array inside the scmi_hwmon_probe function:
drivers/hwmon/scmi-hwmon.c:226
scmi_hwmon_probe() error: buffer overflow 'hwmon_attributes' 6 <= 9
Fix it by statically declaring the size of the array as the maximum
possible as defined by hwmon_max define.
