In short, ZoL's Debian then-maintainer (who is not Debian's current ZoL maintainer, if I am not mistaken) built the "official" ZoL Debian packages with additional patches.
Those patches were subject to above's CVE, the issue has since been fixed and affected Debian exclusively.
Just for completeness sake, a CVE was assigned to ZFS on Linux, CVE-2015-3400.
This is based on an issue that was exclusive to Debian.
See http:// www.openwall. com/lists/ oss-security/ 2015/04/ 22/4 for the assignment and https:/ /github. com/zfsonlinux/ zfs/issues/ 3319 for the details.
