"baseSeverity": "HIGH" }, "scenarios": [ { "lang": "en", "value": "AV:N - The faulting code is reached directly from `icmp_rcv()`/`icmpv6_rcv()` on receipt of an RFC 8335 ICMP_EXT_ECHO (type 42) or ICMPV6_EXT_ECHO_REQUEST packet, so any remote host that can route a unicast IP packet to the target triggers it.\nAC:L - A single crafted ICMP packet is sufficient and the attacker fully chooses the target netdevice via the Interface Identification Object (by name, ifindex, or address); on CONFIG_IPV6=n, ipv6-disabled, or low-MTU-interface systems `dev->ip6_ptr` is unconditionally NULL, making the crash 100% deterministic with no race to win and no memory layout to groom.\nPR:N - The PROBE handler runs in softirq packet-receive context with no socket, no authentication, and no capability or credential check anywhere on the path from `ip_local_deliver()` to `icmp_build_probe()`.\nUI:N - The kernel processes the incoming ICMP Extended Echo Request autonomously in the receive path; no local user or administrator action is needed at attack time.\nS:U - The fault occurs in the kernel's own networking receive path and its impact is confined to the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:N - The bug is a read-only dereference at a fixed small offset from NULL that oopses before any value is used; at most a single status bit could be reflected, yielding no kernel memory contents or address disclosure.\nI:N - There is no write primitive — only NULL-pointer loads (`list_empty(&NULL->addr_list)` and `NULL->ifa_list`) — so no kernel memory or control flow can be modified.\nA:H - The NULL dereference oopses in NET_RX softirq context, killing the softirq and panicking the box on `panic_on_oops` systems; an unauthenticated remote attacker can repeat it at will for a persistent remote denial of service." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
