Really?

Because I would call a situation where the development team fails to appreciate the severity of a security vulnerability and has an established procedure that requires the researcher and not the kernel team to communicate with downstream users is already a major failure of process. Security is not just patching the vulnerability, and it seems that the Linux kernel developers or the Linux kernel security team does not understand that.

This is the result of that failure.

If this were any other software, we'd be here with pitchforks and torches. The researcher gave the developers timed disclosure, and even waited until after the developers had patched the issue. And... it's still a problem.
