Although this research is enormously helpful to Zstandard development
(e.g., see the
https://github.com/Cyan4973/zstd/issues/49#issuecomment-150550342
comment), we feel that it may be outside the scope of CVE because
Zstandard cannot yet be considered a "product."

https://github.com/Cyan4973/zstd/blob/master/README.md

Zstd has not yet reached "stable" status. Specifically, it doesn't
guarantee yet that its current compressed format will remain stable
and supported in future versions. ... "Stable Format" is projected
sometimes early 2016

you can now safely test zstd

this format is not yet considered stable.
The objective is to make it stable by year end.
When it will be, the library number will become 1.0.

Also, we think that Zstandard is, for example, not shipped in any
well-known Linux distribution. When a piece of code is offered
primarily for testing, discoveries of exploitable problems often have
low interest among CVE consumers.
