In a way, yes, but most users will probably only find out about this once their CVE tooling reports that they are using a barebox version that doesn't fix e.g. CVE-2025-26722. CVE-2025-26722 (and I assume the others) are reserved right now, but lack a description of the issue and its possible security implications. We should probably write down some extra policy here: - Should CVE numbers even be mentioned for yet-undisclosed issues? - An explicit policy about disclosure timeline. Bugs are fixed all the time and I think, it's desirable that disclosure is postponed until after a release, so users informed of the issue directly know what to do about it. For critical security issues, a point release can be done on short notice @Jonathan, March 19th is ok for us, but we don't object to any earlier date.
