For an IMU report joycon_parse_report()\n-> joycon_parse_imu_report() walks that union (struct offsets 13..48),\nso a report of exactly 12 bytes with data[0] == JC_INPUT_IMU_DATA passes\nthe guard yet is read up to 37 bytes past its declared length. The\nover-read bytes are decoded into accelerometer/gyroscope values and\nforwarded to userspace through the \"(IMU)\" input device, leaking\ndriver-internal memory. data[0] and size are fully controlled by a\nmalicious or spoofed Joy-Con/Pro Controller.\n\nReceive buffers are sized to the maximum report length, so this is an\nover-read within the allocation rather than a slab OOB, but the decoded\nbytes still reach userspace.\n\nThe sibling subcmd path in joycon_ctlr_handle_event() already bounds the\nsame cast correctly:\n\n\tif (size < sizeof(struct joycon_input_report) ||\n\t    data[0] != JC_INPUT_SUBCMD_REPLY)\n\t\tbreak;\n\nUse the same sizeof(struct joycon_input_report) bound here."
