In the Linux kernel, the following vulnerability has been resolved:iio: dummy: iio_simply_dummy_buffer: fix information leak in triggered bufferThe 'data' array is allocated via kmalloc() and it is used to push datato user space from a triggered buffer, but it does not set values forinactive channels, as it only uses iio_for_each_active_channel()to assign new values.Use kzalloc for the memory allocation to avoid pushing uninitializedinformation to userspace.
