An integer underflow vulnerability has been identified in the ESP-NOW protocol implementation within the ESP Wi-Fi component of versions 5.4.1, 5.3.3, 5.2.5, and 5.1.6 of the ESP-IDF framework. This issue stems from insufficient validation of user-supplied data length in the packet receive function. Under certain conditions, this may lead to out-of-bounds memory access and may allow arbitrary memory write operations. On systems without a memory protection scheme, this behavior could potentially be used to achieve remote code execution (RCE) on the target device. In versions 5.4.2, 5.3.4, 5.2.6, and 5.1.6, ESP-NOW has added more comprehensive validation logic on user-supplied data length during packet reception to prevent integer underflow caused by negative value calculations. For ESP-IDF v5.3 and earlier, a workaround can be applied by validating that the `data_len` parameter received in the RX callback (registered via `esp_now_register_recv_cb()`) is a positive value before further processing. For ESP-IDF v5.4 and later, no application-level workaround is available. Users are advised to upgrade to a patched version of ESP-IDF to take advantage of the built-in mitigation.\n\ud83d\udccf Published: 2025-06-24T19:53:06.066Z\n\ud83d\udccf Modified: 2025-06-24T20:02:18.529Z\n\ud83d\udd17 References:\n1. https://github.com/espressif/esp-idf/security/advisories/GHSA-hqhh-cp47-fv5g\n2. https://github.com/espressif/esp-idf/commit/b1a379d57430d265a53aca13d59ddfbf2e7ac409\n3. https://github.com/espressif/esp-idf/commit/c5fc81917805f99e687c81cc56b68dc5df7ef8b5\n4. https://github.com/espressif/esp-idf/commit/d4dafbdc3572387cd4f9a62b776580bc4ac3bde7\n5. https://github.com/espressif/esp-idf/commit/d6ec5a52255b17c1d6ef379e89f9de2c379042f8\n6. https://github.com/espressif/esp-idf/commit/df7757d8279871fa7a2f42ef3962c6c1ec88b8a2\n7. https://github.com/espressif/esp-idf/commit/edc227c5eaeced999b5212943a9434379f8aad80", "url": "https://t.me/DarkWebInformer_CVEAlerts/19404", "metric_role": "exploit_publication", "metric_basis": "sighting_report"}, {"timestamp": "2025-06-25T01:19:51.831Z", "date_only": false, "value": "2025-06-25T01:19:51.831630Z", "kind": "sighting", "label": "Seen", "source": "https://bsky.app/profile/cve.skyfleet.blue/post/3lsfgyxmup22a", "record": "CVE-2025-52471", "field": "creation_timestamp", "uuid": "bcfa788e-f302-4583-ab4a-aa0dff919069", "url": "https://bsky.app/profile/cve.skyfleet.blue/post/3lsfgyxmup22a"}, {"timestamp": "2026-06-17T09:36:33.323Z", "date_only": false, "value": "2026-06-17T09:36:33.323", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2025-52471", "record": "FKIE_CVE-2025-52471", "field": "lastModified", "linked_record": true}], "metrics": {"as_of": "2026-11-10T17:16:41.750Z", "anchors": {"origin": {"timestamp": "2025-06-24T19:53:06.066Z", "date_only": false, "value": "2025-06-24T19:53:06.066Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2025-52471", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2025-06-24T19:53:06.066Z", "date_only": false, "value": "2025-06-24T19:53:06.066Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2025-52471", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "exploit_publication": {"timestamp": "2025-06-24T20:48:01Z", "date_only": false, "value": "2025-06-24T20:48:01.000000Z", "kind": "sighting", "label": "Published proof of concept", "source": "https://t.me/DarkWebInformer_CVEAlerts/19404", "record": "CVE-2025-52471", "field": "creation_timestamp", "uuid": "56ee1ec8-d172-4e36-9952-4574995ec83f", "content": "\ud83d\udd17 DarkWebInformer.com - Cyber Threat Intelligence\n\ud83d\udccc CVE ID: CVE-2025-52471\n\ud83d\udd25 CVSS Score: 7.2 (cvssV4_0, Vector: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U)\n\ud83d\udd39 Description: ESF-IDF is the Espressif Internet of Things (IOT) Development Framework.
