CVE-2024-57906 Information

Description

In the Linux kernel the following vulnerability has been resolved:

iio: adc: ti-ads8688: fix information leak in triggered buffer

The ‘buffer’ local array is used to push data to user space from a triggered buffer but it does not set values for inactive channels as it only uses iio_for_each_active_channel() to assign new values.

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