I still do not understand why you report issues that are fixed over a
year ago (October 2019) and assign them a CVE like this.  Who does this
help out?  And what about the thousands of other issues that are fixed
in the kernel and not assigned a CVE like this, are they somehow not as
important to your group?

What determines what you want to give a CVE to and what you do not?



I think I can answer that.   There's nothing technical going on here,
it's down to the behaviour of the end users of enterprise systems.


Ok, I can understand that crazyness, and somehow believe it, so I have
not complained when announcements like this come out for issues that
affect RHEL releases as RH is known for abusing^using the CVE system in
this manner.  But that was not the case here at all, which is why I
asked this.
