DISA STIG for RHEL 8.2 & Oracle DB 19.3.0

I am trying to run oracle DB 19c on RHEL8.2 with DISA STIG security profile enabled during RHEL installation.

Applied oracle DB installation prerequisites, when I try to start runInstaller I got "Operation Not Permitted".

Cannot find what prevent "oracle" user from running 'perl' while root can do so..

[oracle@rh8-1 ~]$ cd /u01/app/oracle/product/19.3.0/dbhome_1/
[oracle@rh8-1 dbhome_1]$ export CV_ASSUME_DISTID=OEL7.8
[oracle@rh8-1 dbhome_1]$ ./runInstaller
./runInstaller: line 67: /u01/app/oracle/product/19.3.0/dbhome_1/perl/bin/perl: Operation not permitted
