Overview

CVE-2023-52652 is a medium-severity vulnerability. It was published on May 1, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

NTB: fix possible name leak in ntb_register_device()

If device_register() fails in ntb_register_device(), the device name

allocated by dev_set_name() should be freed. As per the comment in

device_register(), callers should use put_device() to give up the

reference in the error path. So fix this by calling put_device() in the

error path so that the name can be freed in kobject_cleanup().

As a result of this, put_device() in the error path of

ntb_register_device() is removed and the actual error is returned.

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.
