Input: kbtab - validate number of endpoints before using them

2017-03-30T07:35:15+00:00

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

2014-07-26T01:55:38+00:00

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

Input: wacom - keep wacom_ids ordered

2014-07-26T01:53:56+00:00

No Functional changes, just some reordering.

Input: wacom - remove field pktlen declaration in the list of devices

2014-07-26T01:53:56+00:00

pktlen is now overwritten by the driver directly by reading the hid
report descriptor. There is no need to declare it statically.
We also move down the position of the field in the struct so that
we can keep the current declaration of Wacom devices.

Input: wacom - use hidinput_calc_abs_res instead of duplicating its code

2014-07-26T01:53:55+00:00

This may infer a small difference with the previous implementation
due to the DIV_ROUND_CLOSEST() in the hid implementation.
