In the Linux kernel, the following vulnerability has been resolved:

HID: wacom: Fix OOB write in wacom_hid_set_device_mode()

wacom_hid_set_device_mode() currently assumes that the HID_DG_INPUTMODE

usage is always located in the first field (field[0]) of the feature report.

However, a device can specify HID_DG_INPUTMODE in a different field.

If HID_DG_INPUTMODE is in a field other than the first one and the first

field has a report_count smaller than the usage_index of HID_DG_INPUTMODE,

this leads to an out-of-bounds write to r->field[0]->value.

Fix this by storing the field index of HID_DG_INPUTMODE in 'struct

hid_data' during feature mapping. In wacom_hid_set_device_mode(), use

this stored field index to access the correct field and add bounds

checks to ensure both the field index and the value index are within

valid ranges before writing. (NVD)
