CVE-2026-43414 is a double-free vulnerability in the Linux kernel's qla2xxx SCSI driver. In qla24xx_els_dcmd_iocb(), the sp->free callback is assigned to qla2x00_els_dcmd_sp_free(). During error handling, kref_put() releases the final reference and qla2x00_sp_release() invokes this callback, which frees the fcport object through qla2x00_free_fcport(). An additional free after kref_put() therefore releases the same object twice. The complete fix addresses an incomplete earlier correction of fcport cleanup.
