"value": "AV:N - In a reasonable affected deployment, a remote peer can send a packet, including GRE traffic, that arrives through a stacked bonding hierarchy and triggers AF_PACKET/NFLOG/NFQUEUE hardware-address parsing on the top bond. The vulnerable code is reached from network packet receive processing, not from a physical or purely local-only interface.\nAC:L - Once the stacked bond and packet metadata consumer exist, a single matching received packet deterministically enters `dev_parse_header()` and recurses indefinitely. There is no race, timing window, heap shaping, or attacker-uncontrolled probabilistic condition needed to trigger the denial of service.\nPR:N - The network-triggered path does not require the remote attacker to authenticate or hold local privileges; they only need to send traffic to the affected interface/tunnel. Although local namespace users can also create a reproducer with CAP_NET_ADMIN/CAP_NET_RAW in their namespace, the highest reasonable scenario requires no attacker privileges.\nUI:N - No victim action is required at exploit time when the affected bond stack and packet logging/capture path are already active. The packet alone triggers the vulnerable parse path.\nS:U - The impact remains within the kernel/networking security authority of the vulnerable system. There is no VM escape, sandbox boundary crossing, or separate security scope affected.\nC:N - The bug is an unbounded recursive call caused by using the top-level `skb-\u003edev`; it does not create an information disclosure or controlled read primitive.\nI:N - The vulnerable path does not corrupt attacker-selected data or provide a write/control-flow primitive; the final lower-device parser is never reached. The observed consequence is recursion leading to denial of service.\nA:H - The infinite recursion can hang kernel packet processing and lead to stack overflow/lockdep exhaustion or kernel crash. This is a high availability impact."

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.
Vulnerability timeline
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.
