Unity Linux 20.1060a / 20.1070a Security Update: kernel (UTSA-2025-993003)

medium Nessus Plugin ID 280984

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-2025-993003 advisory.

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

 net: hns: fix possible memory leak in hnae_ae_register()

 Inject fault while probing module, if device_register() fails, but the refcount of kobject is not decreased to 0, the name allocated in dev_set_name() is leaked. Fix this by calling put_device(), so that name can be freed in callback function kobject_cleanup().
