## Overview

In the Linux kernel, the following vulnerability has been resolved:

iio: adc: ti-ads1298: add bounds check to pga_settings index

ads1298_pga_settings has 7 elements but ADS1298_MASK_CH_PGA can yield
values 0-7. If it yields a value >= 7, this causes an out-of-bounds
array access. Add a bounds check and return -EINVAL if the index
is out of range.

Note that the remaining value b111 is reserved so should not be seen
in a correctly functioning system.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
