Technical description

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

iio: health: afe4403: Fix oob read in afe4403_read_raw

KASAN report out-of-bounds read as follows:

BUG: KASAN: global-out-of-bounds in afe4403_read_raw+0x42e/0x4c0

Read of size 4 at addr ffffffffc02ac638 by task cat/279

Call Trace:

afe4403_read_raw

iio_read_channel_info

dev_attr_show

The buggy address belongs to the variable:

afe4403_channel_leds+0x18/0xffffffffffffe9e0

This issue can be reproduced by singe command:

$ cat /sys/bus/spi/devices/spi0.0/iio\:device0/in_intensity6_raw

The array size of afe4403_channel_leds is less than channels, so access

with chan->address cause OOB read in afe4403_read_raw. Fix it by moving

access before use it.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
