Unity Linux 20.1050e Security Update: kernel (UTSA-2026-021604)

high Nessus Plugin ID 315801

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-2026-021604 advisory.

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

iio: adc: at91: call input_free_device() on allocated iio_dev

Current implementation of at91_ts_register() calls input_free_deivce() on st->ts_input, however, the err label can be reached before the allocated iio_dev is stored to st->ts_input. Thus call input_free_device() on input instead of st->ts_input.

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.
