The Linux project's view is that almost all kernel bugs are security vulnerabilities. They don't treat something like this as anything special.
I can understand that PoV, but it doesn't fit with distributions' approach to security. So, in practice, one has to reach out to distributions individually, or use distros lists on openwall.org to coordinate with all distros.
As far as we can tell, nobody disclosed it to the distributions, only to the kernel security team (who did not reach out to distributions). So the distributions are all scrambling now.
Debian has epochs, but it's a bad idea to use them for this purpose.
Two reasons:
1. Once you bump the epoch, you have to use it forever.
2. The deb filename often doesn't contain the epoch (we use a colon which isn't valid on many filesystems), so an epoch-revert will give the same file name as pre-epoch, which breaks your repository.
So, the current best practice is the +really+ thing.

This drives me nuts, when I have a bunch of native packages I want to bundle in our in-house python deployment. CentOS and Ubuntu are vanilla, and only Debian (mind-boggingly) deviates from the well-trodden path.
Hi, I'm one of the people that look after this bit of Debian (and it's exactly the same in Ubuntu, FWIW).
It's like that to solve a problem (of course, everything has a reason). The idea is that Debian provides a Python that's deeply integrated into Debian packages. But if you want to build your own Python from source, you can. What you build will use site-packages, so it won't have any overlap with Debian's Python.
Unfortunately, while this approach was designed to be something all package-managed distributions could do, nobody else has adopted it, and consequently the code to make it work has never been pushed upstream. So, it's left as a Debian/Ubuntu oddity that confuses people. Sorry about that.
My recommendations are:
1. If you want more control over your Python than you get from Debian's package-managed python, build your own from source (or use a docker image that does that).
2. Deploy your apps with virtualenvs or system-level containers per app.
