Was caused by:
Missing type enforcement (TE) allow rule.

You can use audit2allow to generate a loadable module to allow this access.

$ cat logfile.txt | audit2allow -p SEPOLICY_FILE

allow shell default_android_service:service_manager find;

SELinux is configured in Permissive mode, so it's not the primary issue here. Could you kindly supply complete log files?
