An information leak flaw was found in the way way segmentation was performed on skbs originated from vhost-net when zerocopy feature was enabled. Once the source skb is consumed, ubuf destructor is called and potentially releases the corresponding userspace buffers, which can then for example be repurposed, while the destination skb could still be pointing to the them.
