In the Linux kernel, the following vulnerability has been resolved:
iio: adc: mt6359: fix unchecked return value in mt6358_read_imp
In mt6358_read_imp(), the variable val_v is passed to regmap_read()
but the return value is not checked. If the read fails, val_v remains
uninitialized and its random stack content is subsequently reported
as a measurement result.
Initialize val_v to zero to ensure a predictable value is reported
in case of bus failure and to prevent potential stack data leakage.
This also satisfies static analyzers that might otherwise flag the
variable as used uninitialized.
