Description

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

iio: adc: stm32-adc: fix possible division by zero in processed channel

In case the conversion has failed or returned zero, processing *val can lead to a division by zero. Need to check for errors, or converted value is zero, before processing the data. In case the converted value is zero, e.g. the Vrefint channel, this should be considered as invalid in all cases.
