If the bag is genuinely airtight, then theoretically it's possible. But hugely unlikely that it would happen. The O2 absorbers actually pull a vacuum in the environment (if you use enough of them), so it's not just latching onto whatever oxygen it comes across, it's actively drawing oxygen to itself. Any path that lets air be pulled toward it will be exploited, the oxygen being sucked out toward the absorber.
If concerned about it, a few simple pinpricks in the inner rice bags would fix any worries.
