Title
arp: do not assume dev_hard_header() does not change skb->head
Summary
In the Linux kernel, the following vulnerability has been resolved:
arp: do not assume dev_hard_header() does not change skb->head
arp_create() is the only dev_hard_header() caller
making assumption about skb->head being unchanged.
A recent commit broke this assumption.
Initialize @arp pointer after dev_hard_header() call.

{
"lang": "en",
"value": "AV:L - The demonstrated trigger path is a local rtnetlink sendmsg that changes network device state and causes gratuitous ARP generation through arp_create(). Remote ARP paths can call arp_create(), but the UAF condition depends on locally controlled virtual device/headroom state such as ip6gre stacking.\nAC:L - Once the affected device configuration is present, triggering arp_create() and the ip6gre_header() head expansion is straightforward. Any needed setup or race is controlled by the local attacker through netlink operations.\nPR:L - The relevant rtnetlink operations require CAP_NET_ADMIN in the target network namespace. This is low privilege because an unprivileged local user can obtain CAP_NET_ADMIN in a new user/network namespace on systems with user namespaces enabled.\nUI:N - No victim action is required after the attacker performs the local network configuration and trigger operation. The vulnerable path runs in kernel networking code.\nS:U - The corruption occurs within the kernel networking subsystem and impacts the same kernel security authority. It does not cross a VM, IOMMU, or other separate security boundary.\nC:H - The bug is a slab use-after-free write after pskb_expand_head() moves skb-\u003ehead, leaving arp_create() writing through a stale pointer. Kernel UAF memory corruption can be leveraged for information disclosure, so confidentiality impact is high.\nI:H - The stale ARP header pointer is used for attacker-influenced writes into freed kernel heap memory. This is memory corruption with plausible control-flow or object corruption exploitation, so integrity impact is high.\nA:H - KASAN reports confirm a slab-use-after-free write in arp_create(), and such corruption can directly crash or panic the kernel. Repeated triggering can cause system-wide denial of service."

Sightings and recorded dates, grouped by day · UTC
How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
