In the Linux kernel, the following vulnerability has been resolved:
HID: sensor-hub: Fix out-of-bounds write in sensor_hub_get_feature
sensor_hub_get_feature() clamps its return value to the caller's buffer
size, but the copy loop still copies field->report_size / 8 bytes for
each report value. A malicious HID descriptor can advertise a large
feature field size while an IIO caller supplies a small stack buffer,
such as a single s32, causing an out-of-bounds write.
HID core stores parsed report values in __s32 slots and clamps extracted
values to 32 bits. Reject feature fields that require more than one slot
per value, guard the total byte count calculation, and clamp each
per-value copy to the remaining caller buffer.
