- [docker/cli, 27.4.1 milestone](https://github.com/docker/cli/issues?q=is%3Aclosed+milestone%3A27.4.1)
- [moby/moby, 27.4.1 milestone](https://github.com/moby/moby/issues?q=is%3Aclosed+milestone%3A27.4.1)

#### Bug fixes and enhancements

- Fix excessive memory allocations when OTel is not configured. [moby/moby#49079](https://github.com/moby/moby/pull/49079)
- The `docker info` command and the corresponding `GET /info` API endpoint no longer include warnings when `bridge-nf-call-iptables` or `bridge-nf-call-ip6tables` are disabled at the daemon is started. The `br_netfilter` kernel module is now attempted to be loaded when needed, which made those warnings inaccurate. [moby/moby#49090](https://github.com/moby/moby/pull/49090)
- Attempt to load kernel modules, including `ip6_tables` and `br_netfilter` when required, using a method that is likely to succeed inside a Docker-in-Docker container. [moby/moby#49043](https://github.com/moby/moby/pull/49043)
- Fix a bug that could result in an iptables `DOCKER FILTER` chain not being cleaned up on failure. [moby/moby#49110](https://github.com/moby/moby/pull/49110)

- Update Buildx to [v0.19.3](https://github.com/docker/buildx/releases/tag/v0.19.3). [docker/docker-ce-packaging#1132](https://github.com/docker/docker-ce-packaging/pull/1132)
