I think this needs way more clarification .. how exactly is this going to 
work?

Do I read this correctly that *everything* that lands in -stable will 
automatically get CVE assigned? If so, that's just plain crazy. Just took 
a random peek on the topmost -stable changelog ...

	ASoC: codecs: wsa883x: fix PA volume control
	ASoC: codecs: lpass-wsa-macro: fix compander volume hack
	ASoC: codecs: wcd938x: fix headphones volume controls
	ASoC: qcom: sc8280xp: limit speaker volumes
	drm/amdgpu: Fix missing error code in 'gmc_v6/7/8/9_0_hw_init()'

Only the last one can *potentially* be considered a CVE candidate, but 
someone would actually have to take a *deep* look. Most likely it'll be a 
functional issue, but not a security issue by any measures.

So I hope it's not the case, and someone will actually be doing some 
triage. If that's the case -- is this process described anywhere?

Also, how are the CVSS-like scores going to be assigned? There are no 
details whatsoever about that in the document.

In any case, by making this change we are going to make security theathre 
industry super-happy (they will have a lot of expensive nothing going on), 
and all the distros not basing on -stable very unhappy (we're already 
drowning because everybody and his grandma wants to become famous by 
publishing a CVE for something completely irrelevant). If this is the 
intention, it should be spelled out loud and clear.

Thanks,
