i have no problem with disclosing a vulnerability 30 days after its patched in the thing you reported to. (in fact, for those unaware, this is the same policy that google's project zero uses: "90+30" https://projectzero.google/vulnerability-disclosure-policy.h...)
the real problem is:
>It's also worrying that it seems there's no communication between the kernel security team and distribution maintainers.
the reporter should not be the one responsible for reporting separately to every single downstream of the thing they found a vuln in.
what should be happening, as you allude to, is a communication channel between the kernel security team and distribution maintainers. they are in a much better position to coordinate and communicate with the maintainers than random reporters are.
the minute the patch landed in the kernel, a notification should have gone out from the kernel team to a curated list of distro security folk that communicated the importance of the patch, and that the public disclosure would be in 30 days.
