Your problem has nothing to do with the file being in /tmp.

That's wrong syntax. The <() construct is for process
substitution, not for reading a file.

What you want is simply

exec 3< /tmp/dls1

While that works, you don't need process substitution
or cat there either. Just do

done < /tmp/dls2

> bash: /tmp/dls1: Permission denied

That's because it tries to use /tmp/dsl1 as a command,
and it's not executable.
