A source frame backed by a\nlarger allocation can still satisfy that check while extending into the\nclone's required shared-info area. When such a clone is converted back\ninto an skb, build_skb_around() places skb_shared_info over live packet\nbytes and later writes can corrupt XDP return metadata.\n\nReject clones unless their linear area fits inside\nSKB_WITH_OVERHEAD(PAGE_SIZE), matching the tailroom requirement already\nenforced by the XDP-to-skb conversion path."
