Prior to 0.16.0, the ct_select function in src/kem/frodokem/external/util.c for the FrodoKEM-640, FrodoKEM-976, and FrodoKEM-1344 AES and SHAKE reference variants lacks a value barrier in the Fujisaki-Okamoto implicit-rejection path. When compiled with Clang 17 or later at an affected optimization level such as -Os, the compiler can emit a secret-dependent conditional load, causing the real and rejection secret paths to leave distinguishable cache residency after successful and failed decapsulation. A local attacker able to perform repeated cache-timing measurements may use this oracle as part of a private-key recovery attack. Default -O3 builds vectorize both source loads and do not exhibit the reported behavior, and the advisory does not report the same generated memory-access pattern in NTRU, NTRU-Prime, BIKE, HQC, Classic McEliece, Kyber, or the already-barriered ML-KEM implementation. This issue is fixed in version 0.16.0.\nhttps://www.cve.org/CVERecord?id=CVE-2026-44519https://github.com/open-quantum-safe/liboqs/security/advisories/GHSA-5c97-hp95-vg56https://github.com/open-quantum-safe/liboqs/pull/2431https://github.com/open-quantum-safe/liboqs/commit/d95fc734f5de9bdfc80c8c65d8166b30e9cff5cdhttps://github.com/open-quantum-safe/liboqs/releases/tag/0.16.0#open-quantum-safe #liboqs#CVE_2026_44519#bot", "url": "https://infosec.exchange/users/cve/statuses/117571603793104905"}, {"timestamp": "2026-11-06T22:17:51.403Z", "date_only": false, "value": "2026-11-06T22:17:51.403", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-44519", "record": "FKIE_CVE-2026-44519", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event", "linked_record": true}, {"timestamp": "2026-11-06T22:17:51.403Z", "date_only": false, "value": "2026-11-06T22:17:51.403", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-44519", "record": "FKIE_CVE-2026-44519", "field": "lastModified", "linked_record": true}], "metrics": {"as_of": "2026-11-07T21:24:32.994Z", "anchors": {"origin": {"timestamp": "2026-11-06T21:22:27.624Z", "date_only": false, "value": "2026-11-06T21:22:27.624Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-44519", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2026-11-06T21:22:27.624Z", "date_only": false, "value": "2026-11-06T21:22:27.624Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-44519", "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": 86525.370173, "hours": 24.034825048055556, "days": 1.0014510436689814, "min_seconds": 86525.370173, "max_seconds": 86525.370173, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-11-06T21:22:27.624Z", "date_only": false, "value": "2026-11-06T21:22:27.624Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-44519", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-11-07T21:24:32.994Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}, "exploitation_to_patch": {"available": false, "missing": ["start"]}, "exploit_publication_to_patch": {"available": false, "missing": ["start"]}}}
