CVE-2026-80590

CVE-2026-80590 is a Linux kernel vulnerability in the IP fragment reassembly code path (inet: frags ). A virtio_net_hdr (via tun/tap or AF_PACKET) can mark an IPv4/IPv6 fragment as GSO; after reassembly the reassembled skb retains this GSO state, and the subsequent call to skb_segment() — which a...
