In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
platform\/chrome: sensorhub: Bound the EC-reported sensor number<\/p>\n
Each EC FIFO event carries an 8-bit sensor number (in->sensor_num).
\ncros_ec_sensorhub_ring_handler() validates the FIFO event count, the
\nper-read count and the ring bound, but not the sensor number, which
\ncros_ec_sensor_ring_process_event() then uses unchecked to index
\nsensorhub->batch_state[] – allocated with only sensorhub->sensor_num
\nentries. A sensor number of sensor_num or larger is an out-of-bounds
\nread and write of batch_state[].<\/p>\n
Validate the sensor number in the ring handler, where each event is read
\nfrom the EC, and drop a malformed event before it is used.<\/p>\n","protected":false},"excerpt":{"rendered":"
