Technical description

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

macintosh: fix possible memory leak in macio_add_one_device()

Afer commit 1fa5ae857bb1 ("driver core: get rid of struct device's

bus_id string array"), the name of device is allocated dynamically. It

needs to be freed when of_device_register() fails. Call put_device() to

give up the reference that's taken in device_initialize(), so that it

can be freed in kobject_cleanup() when the refcount hits 0.

macio device is freed in macio_release_dev(), so the kfree() can be

removed.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
