Overview

Technical description

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

scsi: qla2xxx: Completely fix fcport double free

In qla24xx_els_dcmd_iocb() sp->free is set to qla2x00_els_dcmd_sp_free().

When an error happens, this function is called by qla2x00_sp_release(),

when kref_put() releases the first and the last reference.

qla2x00_els_dcmd_sp_free() frees fcport by calling qla2x00_free_fcport().

Doing it one more time after kref_put() is a bad idea.

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.
