The load pass then recomputes the count in a narrower type and writes attacker-controlled glyph records into the undersized buffer.\nhttps://www.cve.org/CVERecord?id=CVE-2026-91189https://github.com/eclipse-threadx/guix/security/advisories/GHSA-hgcj-22cg-4hfv#EclipseFoundation #EclipseThreadX-GUIX#CVE_2026_91189#bot", "url": "https://infosec.exchange/users/cve/statuses/117473839621959015"}, {"timestamp": "2026-10-20T15:17:36.167Z", "date_only": false, "value": "2026-10-20T15:17:36.167", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-91189", "record": "FKIE_CVE-2026-91189", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event"}, {"timestamp": "2026-10-20T15:24:56.279Z", "date_only": false, "value": "2026-10-20T15:24:56.279111Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-91189", "field": "containers.adp.0.metrics.0.other.content.timestamp"}, {"timestamp": "2026-10-20T15:24:56.279Z", "date_only": false, "value": "2026-10-20T15:24:56.279111Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-91189", "record": "FKIE_CVE-2026-91189", "field": "metrics.ssvcV203.0.ssvcData.timestamp"}, {"timestamp": "2026-10-20T15:25:24.066Z", "date_only": false, "value": "2026-10-20T15:25:24.066Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2026-91189", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-10-20T15:25:24.066Z", "date_only": false, "value": "2026-10-20T15:25:24.066Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-91189", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-10-20T19:48:50.250Z", "date_only": false, "value": "2026-10-20T19:48:50.250", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-91189", "record": "FKIE_CVE-2026-91189", "field": "lastModified"}], "metrics": {"as_of": "2026-10-31T09:14:24.222Z", "anchors": {"origin": {"timestamp": "2026-10-20T14:53:44.860Z", "date_only": false, "value": "2026-10-20T14:53:44.860Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-91189", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2026-10-20T14:53:44.860Z", "date_only": false, "value": "2026-10-20T14:53:44.860Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-91189", "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": 930039.362275, "hours": 258.3442672986111, "days": 10.764344470775463, "min_seconds": 930039.362275, "max_seconds": 930039.362275, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-10-20T14:53:44.860Z", "date_only": false, "value": "2026-10-20T14:53:44.860Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-91189", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-10-31T09:14:24.222Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}, "exploitation_to_patch": {"available": false, "missing": ["start"]}, "exploit_publication_to_patch": {"available": false, "missing": ["start"]}}}
