Technical description
In the Linux kernel, the following vulnerability has been resolved:
vxlan: fix reading neigh ha
Currently arp/neigh_reduce read neigh ha directly which can lead to
partial reads while the neigh is being updated. Use neigh_ha_snapshot to
take a stable snapshot of the address similar to route_shortcircuit which
already does the right thing.
