In the Linux kernel, the following vulnerability has been resolved:
virtio-net: zero unused hash fields
When GSO tunnel is negotiated virtio_net_hdr_tnl_from_skb() tries to
initialize the tunnel metadata but forget to zero unused rxhash
fields. This may leak information to another side. Fixing this by
zeroing the unused hash fields.
