Bundling the following into a single CVE:

Please use CVE-2012-6138 for these issues.

I think this is wrong.  I would understand if those issues
were all in the same subsystem at least (or if you assigned 
per-subsystem CVE IDs for these), but this is not the case.
Many distros will fix some, but not the others, or not all at
the same time.  There's room for a little bit of bundling here,
but not that much.

In the past we've usually assigned one CVE per issue even for
info leak bugs. Or at least one CVE per subsystem, as Alexander
says. I agree with Alexander that one CVE for about ~20 issues is
not right.

So, are all CVE-IDs assigned before are invalid now? I just want to
make sure I didn't pollute our databases. :)

Cheers,

Agreed (I was wrong, not much more to say than that =). It sounds
like Mitre will be handling the additional CVEs for this issue as
I understand it.

Now my question is how concise do we go with the Linux kernel as
far as subsystems go? E.g. file subsystem vs network subsystem
seems obvious, and say ext4 vs. MSDOS file system code seems
obvious but what about network drivers (same chipset? same maker,
different chipsets? or like ext2 vs ext3 vs ext4).
