Description
Description
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).
