Yes.  If a system allows a user with privilege less than
secpolicy_ucode_update() to write to /platform/i86pc/ucode, which is of
the following mode,

    d none platform/i86pc/ucode 755 root sys

then this user will be able to arrange microcode update by writing it
to the location to be used on subsequent boot.
