metalink [ID 1069517.1]:
In environment where listener home (including SCAN listener which
resides in Grid Infrastructure/ASM home) and database home are owned by
different OS user, ORA-12537 could happen when connecting through
listener, when creating database through DBCA, or when
installing database software and creating a database in runInstaller.
Job Role Separation is a typical example as SCAN and local grid home
listener is owned differently than database.
// *Cause: "End of file" condition has been reached; partner has disconnected.
// *Action: None needed; this is an information message.

Solution is to make sure file system for database home has setuid/suid
set, database binary($RDBMS_HOME/bin/oracle) has correct ownership and
permission, and listener owner is able to access database oracle binary
(as listener owner, "ls -l $RDBMS_HOME/bin/oracle"
will tell)
