Yup, and runc as well; I pasted both errors in a PR there; opencontainers/runc#3813 (comment)


### Bug fixes and enhancements

- Fixed a number of issues that can cause Swarm encrypted overlay networks
to fail to uphold their guarantees, addressing [CVE-2023-28841](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-28841),
[CVE-2023-28840](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-28840), and
[CVE-2023-28842](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-28842).
- A lack of kernel support for encrypted overlay networks now reports
as an error.
- Encrypted overlay networks are eagerly set up, rather than waiting for
multiple nodes to attach.
- Encrypted overlay networks are now usable on Red Hat Enterprise Linux 9
through the use of the `xt_bpf` kernel module.
- Users of Swarm overlay networks should review [GHSA-vwm3-crmr-xfxw](https://github.com/moby/moby/security/advisories/GHSA-vwm3-crmr-xfxw)
to ensure that unintentional exposure has not occurred.

### Packaging Updates

- Upgrade `containerd` to [v1.6.20](https://github.com/containerd/containerd/releases/tag/v1.6.20).
- Upgrade `runc` to [v1.1.5](https://github.com/opencontainers/runc/releases/tag/v1.1.5).
