We received a slab-out-of-bounds report in ip6_xmit() for KASAN build on 4.9 kernel. The patches that fix this issue have been backported to to stable 4.14 and one of them even to 3.16 but 4.9 stable branch does not include them. Backport to linux-4.9.y required trivial merge conflict resolution. They cleanly apply to linux-stable linux-4.9.y branch tagged v4.9.249.
