## Overview

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.

## Affected

- `linux_kernel >= 5.15.154, < 5.16`
- `linux_kernel >= 6.1.84, < 6.2`
- `linux_kernel >= 6.6.24, < 6.7`
- `linux_kernel >= 6.7.12, < 6.8`
- `linux_kernel >= 6.8.3, < 6.9`
- `linux_kernel >= 6.9.1, < 6.19.9`
- `linux_kernel = 6.9`
- `linux_kernel = 7.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.19.9`
