Unity Linux 20.1060a / 20.1070a Security Update: kernel (UTSA-2025-993036)

medium Nessus Plugin ID 280861

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-2025-993036 advisory.

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

 remoteproc: k3-r5: Fix refcount leak in k3_r5_cluster_of_init

 Every iteration of for_each_available_child_of_node() decrements the reference count of the previous node.
 When breaking early from a for_each_available_child_of_node() loop, we need to explicitly call of_node_put() on the child node.
 Add missing of_node_put() to avoid refcount leak.

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.
