Duly noted, but I have something to say anyway ;-) From a CVE purist perspective, successful exploitation gets something more than what you can get with CAP_NET_RAW alone, thus there is a violation of the intended security model, no matter how small. One exception that I sometimes wonder about is whether you already have chained privileges  (e.g. where legitimate use of privilege A can automatically get you privilege B), but that kind of thing sometimes makes me wonder why there are 2 separate privileges in the first place. So, it would be reasonable to have a CVE, even though its severity would be knocked way down because of the combination of the minor infoleak and requirements for already-high privileges. I recognize that this approach is probably at odds with many developers who have to implement protection mechanisms related to privileges and access control. - Steve  where "privilege" is placeholder for "privilege, capability, access, permission, etc., whatever the term is that is used for the particular software you have in mind that is an implicit or explicit statement of what a particular user or group of users is allowed to do."
