Unity Linux 20.1050a Security Update: kernel (UTSA-2026-146621)

high Nessus Plugin ID 373218

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-2026-146621 advisory.

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

HID: synchronize input before cleaning up a failed probe

hid_device_io_start() allows reports to run concurrently with probe. If the probe subsequently fails, __hid_device_probe() releases driver resources and clears hdev->driver without first excluding those report callbacks.

For example, a report may enter hidraw_report_event() while the failure path frees the associated hidraw object, leading to a use-after-free when the report takes the object's list lock.

Stop input before performing failed-probe cleanup. This reacquires driver_input_lock and waits for any report callback already in progress.

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.
