CVE-2026-43414 is a memory-management vulnerability in the Linux kernel SCSI qla2xxx driver. The flaw is a double-free condition involving fcport objects in the error-handling path associated with qla24xx_els_dcmd_iocb(). In the vulnerable logic, qla24xx_els_dcmd_iocb() assigns sp->free to qla2x00_els_dcmd_sp_free(). When an error occurs, qla2x00_sp_release() invokes that free callback as kref_put() drops the final reference. The callback qla2x00_els_dcmd_sp_free() frees the fcport object via qla2x00_free_fcport(), and the object can then be freed again afterward, resulting in a double free. The issue was addressed upstream as a complete fix for the fcport double-free bug in qla2xxx.
