Summary

The Linux kernel kionix-kx022a IIO accelerometer driver has an incorrect array bounds check. When it converts a register value to an array index, the check accepts the array size as a valid last index, though the last valid index is one less. An out-of-range index passes, and the array is accessed past its end.

Description from the CNA

In the Linux kernel, the following vulnerability has been resolved: iio: accel: kionix-kx022a: Fix array boundary check The driver performs a sanity check for an array size, when converting a register value to an array index. The check incorrectly accepts the sizeof(array) as a last index, when last valid index should be sizeof(array) - 1. Fix the check by bailing out when index >= sizeof(array).
