For every previously unseen flow identifier (quarter stream ID) received in a DATAGRAM frame, tokio-quiche creates and retains new, per-flow state. A remote peer can send DATAGRAMs with many distinct identifiers, causing the per-connection flow map and associated channel state to grow without bound.\nImpactExploitation can exhaust process memory and cause a denial of service. The vulnerable code is used in both client and server configurations, so either role can be affected by a malicious peer. QUIC DATAGRAM support in tokio-quiche is enabled by default through QuicSettings::enable_dgram; applications can disable it by setting this field to false. The vulnerable HTTP/3 path is reachable only when DATAGRAM support is negotiated with the peer. Core quiche and HTTP/3 deployments without DATAGRAM support are not affected. \nMitigationDisable DATAGRAMs in tokio-quiche\u2019s QuicSettings::enable_dgram.\nRemediationUpgrade to tokio-quiche version 0.23.0 or later. The fixed code creates flow state only for valid DATAGRAM-capable request streams, which are bounded by QUIC\u2019s stream limits. To tolerate packet reordering, servers retain early DATAGRAMs in a bounded, expiring buffer, while clients discard DATAGRAMs for unknown flows.\nhttps://www.cve.org/CVERecord?id=CVE-2026-12708https://www.cve.org/CVERecord?id=CVE-2026-12708#Cloudflare #tokio-quiche#CVE_2026_12708#bot", "url": "https://infosec.exchange/users/cve/statuses/117592390784985552"}, {"timestamp": "2026-11-10T13:42:52.186Z", "date_only": false, "value": "2026-11-10T13:42:52.186Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2026-12708", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-11-10T13:42:52.186Z", "date_only": false, "value": "2026-11-10T13:42:52.186Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / cloudflare", "record": "CVE-2026-12708", "field": "containers.cna.providerMetadata.dateUpdated"}, {"timestamp": "2026-11-10T14:17:29.980Z", "date_only": false, "value": "2026-11-10T14:17:29.980", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-12708", "record": "FKIE_CVE-2026-12708", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event", "linked_record": true}, {"timestamp": "2026-11-10T14:17:29.980Z", "date_only": false, "value": "2026-11-10T14:17:29.980", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-12708", "record": "FKIE_CVE-2026-12708", "field": "lastModified", "linked_record": true}], "metrics": {"as_of": "2026-11-10T20:16:07.262Z", "anchors": {"origin": {"timestamp": "2026-11-10T13:25:09.558Z", "date_only": false, "value": "2026-11-10T13:25:09.558Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-12708", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2026-11-10T13:25:09.558Z", "date_only": false, "value": "2026-11-10T13:25:09.558Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-12708", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "exploit_publication": null, "exploitation": null, "patch": null}, "vendor_response_time": {"available": false, "missing": ["start", "end"]}, "time_to_exploit": {"available": false, "missing": ["end"]}, "disclosure_to_exploit": {"available": false, "missing": ["end"]}, "disclosure_to_exploit_publication": {"available": false, "missing": ["end"]}, "time_to_patch": {"available": false, "missing": ["start", "end"]}, "total_time_to_patch": {"available": false, "missing": ["start", "end"]}, "disclosure_to_patch": {"available": false, "missing": ["end"]}, "time_unpatched": {"available": true, "seconds": 24657.704078, "hours": 6.849362243888889, "days": 0.28539009349537037, "min_seconds": 24657.704078, "max_seconds": 24657.704078, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-11-10T13:25:09.558Z", "date_only": false, "value": "2026-11-10T13:25:09.558Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-12708", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-11-10T20:16:07.262Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}, "exploitation_to_patch": {"available": false, "missing": ["start"]}, "exploit_publication_to_patch": {"available": false, "missing": ["start"]}}}
