Overview

CVE-2023-53436 is a medium-severity vulnerability. It was published on September 18, 2025 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:

scsi: snic: 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 give up the reference in the error path. So fix this by calling

put_device(), then the name can be freed in kobject_cleanp().

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.
