OK, so what is the point of having CVE assigned to such a commit without
any addional information which is already referenced by the kernel sha?
What is the actual added value of that CVE?

Thanks this gave me some idea. One worrying part is
: Please note that only supported kernel versions have fixes applied to
: them.  For a full list of currently supported kernel versions, please
: see https://www.kernel.org/

am pretty sure there are _fully_ supported kernels outside of that list
which are actively maintained.
