To easily identify the patches that solves CVEs, it was decided to add a tag in the metadata. Current patches in OE-core doesn't have this tag, it is necessary to tag these patches.
My awesome tooling (github:rossburton/ross-tools, patchreview.py) is being updated right now and currently says this for oe-core: Patches missing CVE: 35 (2%) That's an estimate as it just looks for patches that have a CVE identifier in their content or filename, but that could be worse!
Thanks Ross for the tool. I hack a little to try to find more CVE patches, but I couldn't find more. Sent patch to the list with these 35 recipes. http://lists.openembedded.org/pipermail/openembedded-core/2016-January/115127.html
