CVE-2024-57907

iio: adc: rockchip_saradc: fix information leak in triggered buffer

State: Published
Severity: 7.1 High
Published: Jan 19, 2025
Updated: May 11, 2026
Reserved: Jan 19, 2025

Description

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

iio: adc: rockchip_saradc: fix information leak in triggered buffer

The 'data' local struct 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 struct to zero before using it to avoid pushing uninitialized information to userspace.
