path (ipv6_rcv to ip6_protocol_deliver_rcu) by sending fragmented IPv6 packets to an Internet-facing host running IPv6 reassembly on a VRF/L3-master ingress path.\\nAC:L - An attacker can repeatedly deliver IPv6 fragments and time them against concurrent netdev unregister (link teardown, container veth removal, or ip link del with CAP_NET_ADMIN in a user namespace), controlling both sides of the race rather than depending on uncontrollable layout.\\nPR:N - Sending unauthenticated IPv6 fragments requires no kernel credentials; VRF/L3-master configuration is a deployment condition on routers and cloud hosts, not a privilege the attacker must hold to deliver the triggering traffic.\\nUI:N - Exploitation needs only network delivery of fragmented IPv6 packets during interface teardown; no victim action such as opening files, clicking links, or mounting filesystems is required.\\nS:U - The NULL dereference crashes the kernel on the receiving host but does not cross a VM, container, or IOMMU security boundary; impact stays within the same kernel security authority.\\nC:N - The failure is a NULL pointer read in __in6_dev_get(NULL) after dev_get_by_index_rcu() returns NULL; there is no use-after-free, out-of-bounds read, or other information-disclosure primitive.\\nI:N - The bug dereferences a NULL net_device pointer for statistics lookup only; it provides no memory write, corruption, or control-flow hijack primitive beyond crashing the kernel.\\nA:H - The NULL dereference during IPv6 fragment receive/reassembly processing in softirq context causes a kernel OOPS or panic, fully denying availability on the affected system until reboot.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\",
