I do not have a simple reproducer for this.
This is just regularly popping up with custom deployment tooling as part of a large plan.
sudo nerdctl container run -d --name dns --hostname dns-magnetar.local --read-only --restart always --cap-add NET_BIND_SERVICE --env LOG_LEVEL=info --env DNS_STUFF_MDNS=false --network hadron-bridge --publish 4242:4242/tcp --volume data-dns:/magnetar/user/data --label org.hadron.core.version=v0.1-dev --label org.hadron.plan.description=some_plan_descriptor --label org.hadron.plan.name=plan_name --label org.hadron.plan.sha=7841eb9910d7b9d49f49e5940a73ca9d9a0dd6c4975640fd5eea4b39f5376744 --label org.hadron.plan.tag=2025/05/22-14:06:09-2EF02181-EF3C-4E68-9218-3C66599DC459 dubodubonduponey/dns:bookworm-2024-09-01

The error comes (obviously) from CNI bridge (func ensureAddr(br netlink.Link, family int, ipn *net.IPNet, forceAddress bool) error {), and suggests that netlink.Attrs in certain circumstances fails to produce an actual hardware addr.
