+Subject: net/virtio: fix Rx checksum calculation
+
+If hdr->csum_start is larger than packet length, the len argument passed
+to rte_raw_cksum_mbuf() overflows and causes a segmentation fault.
+
+Ignore checksum computation in this case.
+
+CVE-2024-11614
+
+Fixes: ca7036b4af3a ("vhost: fix offload flags in Rx path")
