Description

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

iio: light: vcnl4035: fix information leak in triggered buffer

The 'buffer' local array is used to push data to userspace from a
triggered buffer, but it does not set an initial value for the single
data element, which is an u16 aligned to 8 bytes. That leaves at least
4 bytes uninitialized even after writing an integer value with
regmap_read().

Initialize the array to zero before using it to avoid pushing
uninitialized information to userspace.
