Prior to 1.2.5, `OPEN TYPE` decoding can dereference an unallocated member pointer and crash the consuming program. `OPEN_TYPE_aper_get` in `OPEN_TYPE_aper.c`, `OPEN_TYPE_ber_get` in `OPEN_TYPE_ber.c`, `OPEN_TYPE_oer_get` in `OPEN_TYPE_oer.c`, and `OPEN_TYPE_uper_get` in `OPEN_TYPE_uper.c` share the pattern: a conditional null check on `*memb_ptr2` resets presence only when the member exists, but execution then unconditionally computes an inner value from that pointer and a member offset. If the `OPEN TYPE` member has not been allocated, the null-pointer arithmetic and subsequent read cause a segmentation fault. The advisory demonstrates UPER and APER crashes for `E2connectionUpdateAcknowledge`, notes that `E2AP` uses APER, and provides a BER reproducer; OER is also explicitly identified as affected. This issue is fixed in version 1.2.5.\nhttps://www.cve.org/CVERecord?id=CVE-2026-62298https://github.com/mouse07410/asn1c/security/advisories/GHSA-rcj5-gcvg-x796https://github.com/mouse07410/asn1c/commit/3f7d3bbac8cd195d552945e79586ca5000f33280https://github.com/mouse07410/asn1c/commit/71ae41bd1cb146a432a39f72010b48f45ad69463https://github.com/mouse07410/asn1c/releases/tag/v1.2.5#mouse07410 #asn1c#CVE_2026_62298#bot", "url": "https://infosec.exchange/users/cve/statuses/117531446911990222"}, {"timestamp": "2026-10-30T19:18:33.027Z", "date_only": false, "value": "2026-10-30T19:18:33.027", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-62298", "record": "FKIE_CVE-2026-62298", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event", "linked_record": true}, {"timestamp": "2026-10-30T21:18:14.628Z", "date_only": false, "value": "2026-10-30T21:18:14.628986Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-62298", "field": "containers.adp.0.metrics.0.other.content.timestamp"}, {"timestamp": "2026-10-30T21:18:14.628Z", "date_only": false, "value": "2026-10-30T21:18:14.628986Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-62298", "record": "FKIE_CVE-2026-62298", "field": "metrics.ssvcV203.0.ssvcData.timestamp", "linked_record": true}, {"timestamp": "2026-10-30T22:15:29.845Z", "date_only": false, "value": "2026-10-30T22:15:29.845Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2026-62298", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-10-30T22:15:29.845Z", "date_only": false, "value": "2026-10-30T22:15:29.845Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-62298", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-10-30T23:17:12.577Z", "date_only": false, "value": "2026-10-30T23:17:12.577", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-62298", "record": "FKIE_CVE-2026-62298", "field": "lastModified", "linked_record": true}], "metrics": {"as_of": "2026-11-11T04:05:49.653Z", "anchors": {"origin": {"timestamp": "2026-10-30T18:56:59.029Z", "date_only": false, "value": "2026-10-30T18:56:59.029Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-62298", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2026-10-30T18:56:59.029Z", "date_only": false, "value": "2026-10-30T18:56:59.029Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-62298", "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": 983330.624928, "hours": 273.14739581333333, "days": 11.381141492222223, "min_seconds": 983330.624928, "max_seconds": 983330.624928, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-10-30T18:56:59.029Z", "date_only": false, "value": "2026-10-30T18:56:59.029Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-62298", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-11-11T04:05:49.653Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}, "exploitation_to_patch": {"available": false, "missing": ["start"]}, "exploit_publication_to_patch": {"available": false, "missing": ["start"]}}}
