Unity Linux 20.1070e Security Update: kernel (UTSA-2026-013269)

medium Nessus Plugin ID 308128

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-2026-013269 advisory.

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

media: v4l2-core: Fix a potential resource leak in v4l2_fwnode_parse_link()

If fwnode_graph_get_remote_endpoint() fails, 'fwnode' is known to be NULL, so fwnode_handle_put() is a no-op.

Release the reference taken from a previous fwnode_graph_get_port_parent() call instead.

Also handle fwnode_graph_get_port_parent() failures.

In order to fix these issues, add an error handling path to the function and the needed gotos.

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.
