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.
