Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2025-992382)

medium Nessus Plugin ID 280499

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-2025-992382 advisory.

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

 parisc: led: Fix potential null-ptr-deref in start_task()

 start_task() calls create_singlethread_workqueue() and not checked the ret value, which may return NULL. And a null-ptr-deref may happen:

 start_task() create_singlethread_workqueue() # failed, led_wq is NULL queue_delayed_work() queue_delayed_work_on()
 __queue_delayed_work() # warning here, but continue
 __queue_work() # access wq->flags, null-ptr-deref

 Check the ret value and return -ENOMEM if it is NULL.

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.
