Overview

CVE-2025-38695 is a medium-severity vulnerability. It was published on September 4, 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: lpfc: Check for hdwq null ptr when cleaning up lpfc_vport structure

If a call to lpfc_sli4_read_rev() from lpfc_sli4_hba_setup() fails, the

resultant cleanup routine lpfc_sli4_vport_delete_fcp_xri_aborted() may

occur before sli4_hba.hdwqs are allocated. This may result in a null

pointer dereference when attempting to take the abts_io_buf_list_lock for

the first hardware queue. Fix by adding a null ptr check on

phba->sli4_hba.hdwq and early return because this situation means there

must have been an error during port initialization.

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.
