Subject: [PATCH 4.9 45/62] HID: Fix assumption that devices have inputs
Date: Mon, 4 Nov 2019 22:45:07 +0100 [thread overview]
Message-ID: <20191104211948.129261642@linuxfoundation.org> (raw)
In-Reply-To: <20191104211901.387893698@linuxfoundation.org>
From: Alan Stern <stern@rowland.harvard.edu>
commit d9d4b1e46d9543a82c23f6df03f4ad697dab361b upstream.
The syzbot fuzzer found a slab-out-of-bounds write bug in the hid-gaff
driver. The problem is caused by the driver's assumption that the
device must have an input report. While this will be true for all
normal HID input devices, a suitably malicious device can violate the
assumption.
The same assumption is present in over a dozen other HID drivers.
This patch fixes them by checking that the list of hid_inputs for the
hid_device is nonempty before allowing it to be used.
