Subject: Re: CVE request: vulnerability in the kernel tty

Please correct me if I am wrong somewhere in this email. I just want to
understand why you said this.

Age does not matter for CVE assigment as far as I can tell.

CVE is defined as "common identifiers for publicly known information-security
vulnerabilities in publicly released software packages".

How is it pointless to request CVE identifier for security issue in kernel or
other software if that software is released and used by some distro or other
entity? How do you calculate how many users are using some kernel if it is
released in public website? Please note that this might be easier for kernel
than some other software like web-application project in GitHub.

One reason I could think of for not requesting CVEs for issues is that it
creates workload to MITRE or other CNA (and in some cases users of CVE when they
are tracking issues). If that is the case could you or MITRE tell me where
should that line be drawn?

Or if this is not the case do you mean that "vulnerability in the kernel tty
subsystem" is not critical enough for CVE? If that is the case how is that

Or even "vulnerability in the kernel tty subsystem" is not a security issue?
