CVE-2021-47099

CVE-2021-47099 targets the Linux kernel veth path where GRO could process shared/cloned skbs when GRO is on, and no XDP program is attached. The fix is to skip the GRO stage for shared or cloned skbs, avoiding potential GRO-related corruption; the patch reverts to netif_receive_skb and introduces...
