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-2026-013864 advisory.

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

coresight: syscfg: Fix memleak on registration failure in cscfg_create_device

device_register() calls device_initialize(), according to doc of device_initialize:

Use put_device() to give up your reference instead of freeing
* @dev directly once you have called this function.

To prevent potential memleak, use put_device() for error handling.
