CentOS 7+ Minimal Secure Solution: (should work with RedHat too)

chcon -Rv --type=mysqld_db_t /YOUR/PATH/

Explanation:

Knowing that you applied the good practice of using secure-file-priv=/YOUR/PATH/ in my.cnf in order to use load data infile sql statement, you still see the following:

ERROR 13 (HY000): Can't get stat of '/YOUR/PATH/FILE.EXT' (Errcode: 13 "Permission denied")

That's caused by SELinux Enforcing mode, it's not secure to change the mode to Permissive or disable SELinux.
In short,

chcon change SELinux security context of a file or files/directories in a similar way to how 'chown' or 'chmod' may be used to change the ownership or standard file permissions of a file.

SELinux Enforcing mode prevents mysqld from accessing directories with secure-context-type default_t, hence we need to change the secure-context-type of our path to mysqld_db_t. To see the current secure-context-type use the command:

ls --directory --scontext /YOUR/PATH/

In case you want to reset/undo the solution, then apply below command:

restorecon -Rv /YOUR/PATH/
