CVE-2026-64552

A flaw was found in the Linux kernel's virtio-net component. A malicious virtio backend can exploit an insufficient length check in the receivebig function, leading to an out-of-bounds write. This vulnerability can result in a denial of service DoS due to system instability or crashes...

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...
