Overview

Technical description

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

iio: health: afe4404: Fix oob read in afe4404_[read|write]_raw

KASAN report out-of-bounds read as follows:

BUG: KASAN: global-out-of-bounds in afe4404_read_raw+0x2ce/0x380

Read of size 4 at addr ffffffffc00e4658 by task cat/278

Call Trace:

afe4404_read_raw

iio_read_channel_info

dev_attr_show

The buggy address belongs to the variable:

afe4404_channel_leds+0x18/0xffffffffffffe9c0

This issue can be reproduce by singe command:

$ cat /sys/bus/i2c/devices/0-0058/iio\:device0/in_intensity6_raw

The array size of afe4404_channel_leds and afe4404_channel_offdacs

are less than channels, so access with chan->address cause OOB read

in afe4404_[read|write]_raw. Fix it by moving access before use them.

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.
