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-2026-007331 advisory.

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

 HSI: omap_ssi: Fix refcount leak in ssi_probe

 When returning or breaking early from a for_each_available_child_of_node() loop, we need to explicitly call of_node_put() on the child node to possibly release the node.
