Title
HID: sensor-hub: Fix out-of-bounds write in sensor_hub_get_feature
Summary
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.
