HID: elan: Fix potential double free in elan_input_configured

2022-06-09T08:25:40+00:00

[ Upstream commit 1af20714fedad238362571620be0bd690ded05b6 ]

'input' is a managed resource allocated with devm_input_allocate_device(),
so there is no need to call input_free_device() explicitly or
there will be a double free.

According to the doc of devm_input_allocate_device():
 * Managed input devices do not need to be explicitly unregistered or
 * freed as it will be done automatically when owner device unbinds from
 * its driver (or binding fails).

HID: bigben: fix slab-out-of-bounds Write in bigben_probe

2022-06-09T08:25:24+00:00

[ Upstream commit fc4ef9d5724973193bfa5ebed181dba6de3a56db ]

There is a slab-out-of-bounds Write bug in hid-bigbenff driver.
The problem is the driver assumes the device must have an input but
some malicious devices violate this assumption.

Fix this by checking hid_device's input is non-empty before its usage.

such as X1 tablet for X12 tablet, so that the trackpoint and buttons
can work.

This patch was applied and tested working on 5.17.1 .

HID: apple: Report Magic Keyboard 2021 with fingerprint reader battery over USB

2022-04-13T17:27:15+00:00

[ Upstream commit cbfcfbfc384890a062a5d0cc4792df094a6cc7a8 ]

Like the Apple Magic Keyboard 2015, when connected over USB, the 2021
version with fingerprint reader registers 2 different interfaces. One of
them is used to report the battery level.

However, unlike when connected over Bluetooth, the battery level is not
reported automatically and it is required to fetch it manually.

Add the APPLE_RDESC_BATTERY quirk to fix the battery report descriptor
and manually fetch the battery level.

Tested with the ANSI variant of the keyboard with and without numpad.
