Unity Linux 20.1050e Security Update: kernel (UTSA-2026-005166)

medium Nessus Plugin ID 296959

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-2026-005166 advisory.

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

 fsl/fman: Fix refcount handling of fman-related devices

 In mac_probe() there are multiple calls to of_find_device_by_node(), fman_bind() and fman_port_bind() which takes references to of_dev->dev.
 Not all references taken by these calls are released later on error path in mac_probe() and in mac_remove() which lead to reference leaks.

 Add references release.

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.
