Unity Linux 20.1070e Security Update: kernel (UTSA-2025-992171)

medium Nessus Plugin ID 280446

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-2025-992171 advisory.

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

 scsi: core: Fix possible memory leak if device_add() fails

 If device_add() returns error, the name allocated by dev_set_name() needs be freed. As the comment of device_add() says, put_device() should be used to decrease the reference count in the error path. So fix this by calling put_device(), then the name can be freed in kobject_cleanp().

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.
