Overview

CVE-2023-53124 is a medium-severity vulnerability. It was published on May 2, 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: mpt3sas: Fix NULL pointer access in mpt3sas_transport_port_add()

Port is allocated by sas_port_alloc_num() and rphy is allocated by either

sas_end_device_alloc() or sas_expander_alloc(), all of which may return

NULL. So we need to check the rphy to avoid possible NULL pointer access.

If sas_rphy_add() returned with failure, rphy is set to NULL. We would

access the rphy in the following lines which would also result NULL pointer

access.

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.
