Hi Greg,

commit e39d200fa "KVM: Fix stack-out-of-bounds read in write_mmio" is upstream in latest 4.15-rc tags, is also in long term 3.16.52+ and 3.2.97+ stable kernels, and in latest Fedora kernels, but is missing from 4.14, 4.9, 4.4, 4.1 stable branches.

I think the patch author missed the CC to stable@vger.kernel.org

It might be good to consider picking it up into the stable kernels to ensure long term stable and distro kernels don't diverge too much from more recent stable kernel branches.

Thanks, now picked up.

I wonder how it got into the 3.16 and 3.2 kernels :(

Also, always cc: stable@vger.kernel.org so that all of the stable maintainers can see it, as I am not in charge of all of them (i.e. 4.1)

thanks,

greg k-h
