Sorry I don't understand. Do you mean your Dom0 is 2.6.18? My patches
are against 3.10, the backporting is undergoing, however I don't think
they will be backported to 2.6.18. If you're running 2.6.18 Dom0,
presumably who backported XSA-39 will also backport those patches?
Jan maintains 2.6.18 tree with minimum required patches applied to fix
your problem (Frag bigger than frame), you might want to have a look at
the last two patches in tree.
