CVE-2026-64552

Summary (CVE-2026-64552) In the Linux kernel virtio-net, receive_big() does a length check against (big_packets_num_skbfrags + 1) * PAGE_SIZE, but a gap remains due to add_recvbuf_big() placing sg[1] after the padded vnet header. A malicious virtio backend can announce a length in that gap, causi...
