Input: wacom_serial4 - add support for Wacom ArtPad II tablet

2019-03-23T07:44:28+00:00

commit 44fc95e218a09d7966a9d448941fdb003f6bb69f upstream.

Tablet initially begins communicating at 9600 baud, so this command
should be used to connect to the device:

    $ inputattach --daemon --baud 9600 --wacom_iv /dev/ttyS0

Input: gtco - fix potential out-of-bound access

2017-11-02T08:40:49+00:00

commit a50829479f58416a013a4ccca791336af3c584c7 upstream.

parse_hid_report_descriptor() has a while (i < length) loop, which
only guarantees that there's at least 1 byte in the buffer, but the
loop body can read multiple bytes which causes out-of-bounds access.

commit cb1b494663e037253337623bf1ef2df727883cb7 upstream.

Make sure to check the number of endpoints to avoid dereferencing a
NULL-pointer should a malicious device lack endpoints.

Input: gtco - fix crash on detecting device without endpoints

2016-05-04T21:48:45+00:00

commit 162f98dea487206d9ab79fc12ed64700667a894d upstream.

The gtco driver expects at least one valid endpoint. If given malicious
descriptors that specify 0 for the number of endpoints, it will crash in
the probe function. Ensure there is at least one endpoint on the interface
before using it.

Also let's fix a minor coding style issue.

The full correct report of this issue can be found in the public
Red Hat Bugzilla:

Input: aiptek - fix crash on detecting device without endpoints

2015-12-02T17:35:41+00:00

The aiptek driver crashes in aiptek_probe() when a specially crafted USB
device without endpoints is detected. This fix adds a check that the device
has proper configuration expected by the driver. Also an error return value
is changed to more matching one in one of the error paths.

Merge branch 'wacom' into next

2014-08-07T06:31:48+00:00

Merge large update to Wacom driver, converting it from USB to a HID
driver and unifying wired and bluetooth support, from Benjamin
Tissoires.

Input: wacom - move the USB (now hid) Wacom driver in drivers/hid

wacom.ko is now a full HID driver, we have to move it into the proper
subdirectory: drivers/hid.
