Would it mean that a malicious application being run in non-admin mode by one user could see data/memory in use by an admin user?

    It would indeed imply that which is why this vulnerability is also serious for single user contexts.

    The vulnerability is caused by memory optimization features in Intel processors that unintentionally reveal internal hardware registers to software. This allows untrusted software to access data stored by other programs, which should not normally be accessible.
