At present it looks to me like the embargo was broken by someone identifying the patch as fixing a vulnerability, not someone leaking the mailing list.

More information may come out, or I might be missing something, but assuming that the above is accurate, this isn't a problem with responsible disclosure or mailing list opsec; it's a problem with the nature of open source. Right? Or are folks seriously proposing that the patch/mitigations should have been circulated to distro maintainers privately before going to mainline?
