Prior to 0.16.0, OQS_KEM_encaps_derand can dereference an uninitialized encaps_derand function pointer when called on NTRU-HPS-2048-509, NTRU-HPS-2048-677, NTRU-HPS-4096-821, NTRU-HPS-4096-1229, NTRU-HRSS-701, or NTRU-HRSS-1373. The affected NTRU constructors omit the OQS_KEM.encaps_derand member because those schemes do not support derandomized encapsulation, OQS_KEM objects are allocated without zero initialization, and the wrapper in src/kem/kem.c checks only that the OQS_KEM pointer is non-null before calling through the residual heap value. An application is affected only if it instantiates one of those six NTRU KEMs and invokes OQS_KEM_encaps_derand on it. The supported impact is a calling-process crash and denial of service. This issue is fixed in version 0.16.0.\nhttps://www.cve.org/CVERecord?id=CVE-2026-47738https://github.com/open-quantum-safe/liboqs/security/advisories/GHSA-jr5q-r9qx-v738https://github.com/open-quantum-safe/liboqs/pull/2460https://github.com/open-quantum-safe/liboqs/commit/80ceff0207658eba98bae8eb22ca3aa2a364f40bhttps://github.com/open-quantum-safe/liboqs/releases/tag/0.16.0#open-quantum-safe #liboqs#CVE_2026_47738#bot", "url": "https://infosec.exchange/users/cve/statuses/117571627142653291"}, {"timestamp": "2026-11-06T22:17:51.630Z", "date_only": false, "value": "2026-11-06T22:17:51.630", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-47738", "record": "FKIE_CVE-2026-47738", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event", "linked_record": true}, {"timestamp": "2026-11-06T22:17:51.630Z", "date_only": false, "value": "2026-11-06T22:17:51.630", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-47738", "record": "FKIE_CVE-2026-47738", "field": "lastModified", "linked_record": true}], "metrics": {"as_of": "2026-11-08T00:10:10.741Z", "anchors": {"origin": {"timestamp": "2026-11-06T21:23:45.399Z", "date_only": false, "value": "2026-11-06T21:23:45.399Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-47738", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2026-11-06T21:23:45.399Z", "date_only": false, "value": "2026-11-06T21:23:45.399Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-47738", "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": 96385.342895, "hours": 26.77370635972222, "days": 1.1155710983217593, "min_seconds": 96385.342895, "max_seconds": 96385.342895, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-11-06T21:23:45.399Z", "date_only": false, "value": "2026-11-06T21:23:45.399Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-47738", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-11-08T00:10:10.741Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}, "exploitation_to_patch": {"available": false, "missing": ["start"]}, "exploit_publication_to_patch": {"available": false, "missing": ["start"]}}}
