Unity Linux 20.1050a Security Update: kernel (UTSA-2026-146667)

high Nessus Plugin ID 373165

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-2026-146667 advisory.

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

HID: sensor: custom: Fix field sysfs group cleanup on failure

hid_sensor_custom_add_attributes() creates one sysfs group for each custom sensor field. If sysfs_create_group() fails after some groups have already been created, the function returns the error without removing the previously created groups.

Add a local unwind path to remove the groups that were already created.
With enable_sensor exposed only after the field attributes are ready, this path can free sensor_inst->fields without leaving enable_sensor able to access pointers into that array.

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.
