query pg_stat_ssl hang 100%cpu

Hi,
PGv14.8, OS RHEL8, no SSL enabled in this database, we have a lot of client sessions who check it's ssl state by query, all other sessions got done very quickly, but only 1 session hang there in 100% cpu. It looks like abnormal.

select ssl from pg_stat_ssl where pid=pg_backend_pid();

testdb=# select pid,usename,application_name,query_start,xact_start,state_change,wait_event_type,state,query from pg_stat_activity where pid=1245344;
pid | usename | application_name | query_start | xact_start | state_change | wait_event_type |
state | query
