Transfer Ansible variables from one role (running on one host) to another role that is running on another host in the same playbook

I have a playbook that plays different roles on different hosts. Is it possible to transfer a variable from one role running on one host to another role on another host running in the same run? Or any workaround?

playbook
   host1
     role1
       here I get some variables: var1 var2 ...etc
   host2
     role2
       here I need to use var1 var2 ... etc from the above host/role

The task in role1, which sets the variable db, is as follows:

- shell: cd /ACE/conf && grep ^db.url local1.properties | awk -F/ '{print $4}' | awk -F? '{print $1}'
  register: db

UPDATE: on the first host, the values ​​are dynamic, it is like a configuration file that is always updated. After I save the values ​​in variables on host 1 with role1, I then go to host2, run role2 and make stuff with these values ​​from the variables stored in host1.

I tried with hostvars:

{{ hostvars.LBL.db.stdout }}
{{ hostvars['LBL']['db'] }}
{{ hostvars['LBL']['db']['stdout'] }}

:

in get_variables raise Exception("host not found: %s" % hostname) Exception: host not found: LBL

LBL ,

hostvars :

  hosts: LBL
  tasks:
    - command: "ls /bin"
        register: ls_out

- name: test hostvars host2
  hosts: LM
  tasks:
    - debug:
        var: "{{ hostvars['LBL']['ls_out']['stdout'] }}"

:
