  "details": "In the Linux kernel, the following vulnerability has been resolved:  platform/chrome: sensorhub: Fix memory overread in ring handler  `max_response` and `sensor_num` are read from different EC commands:  - `max_response` is from cros_ec_get_proto_info().     ec_dev-\u003emax_response = info-\u003emax_response_packet_size -                                     sizeof(struct ec_host_response);  - `sensor_num` is from cros_ec_get_sensor_count().     sensor_num = cros_ec_get_sensor_count(ec);  With a malfunctioning EC firmware, it is possible that the `msg-\u003einsize` (i.e., `fifo_info_length` in the context) could be clamped in cros_ec_cmd_xfer() because `msg-\u003einsize` is greater than `max_response`.      int fifo_info_length =             sizeof(struct ec_response_motion_sense_fifo_info) +             sizeof(u16) * sensorhub-\u003esensor_num;  This means the number of read bytes could be less than expected.  As a result, the subsequent memcpy() in cros_ec_sensorhub_ring_handler() overreads the `resp-\u003efifo_info` buffer.  Check the return value of cros_ec_cmd_xfer_status() and abort if the number of bytes read does not match the expected length.",
