CVE-2026-93165 is a vulnerability in Linux Kernel
Published on September 17, 2026
platform/chrome: sensorhub: Fix memory overread in ring handler
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->max_response = info->max_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->insize`
(i.e., `fifo_info_length` in the context) could be clamped in
cros_ec_cmd_xfer() because `msg->insize` is greater than `max_response`.
int fifo_info_length =
sizeof(struct ec_response_motion_sense_fifo_info) +
sizeof(u16) * sensorhub->sensor_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->fifo_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.
