Unity Linux 20.1070a Security Update: kernel (UTSA-2025-989057)

high Nessus Plugin ID 273763

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-989057 advisory.

 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.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
