Prior to 5.2.8, 5.3.6, 5.5.5, 6.0.3, and 6.1-rc1, ESP-IDF BlueDroid L2CAP configuration-option processing in l2c_main.c and l2c_utils.c does not consistently validate option lengths against the remaining received packet bytes. A remote unauthenticated BR/EDR peer within radio range can send a malformed L2CAP configuration request that causes an out-of-bounds read, and under some runtime conditions limited adjacent Bluetooth stack memory can be included in an outbound L2CAP Configuration Response. The issue affects ESP32-class products using the BlueDroid host stack with Classic Bluetooth enabled. This issue is fixed in 5.2.8, 5.3.6, 5.5.5, 6.0.3, and 6.1-rc1.\nhttps://www.cve.org/CVERecord?id=CVE-2026-81507https://github.com/espressif/esp-idf/security/advisories/GHSA-v335-fxwc-rc44https://github.com/espressif/esp-idf/commit/14c99559b4337cabcf0f09c21d16b93c4cd7a6fehttps://github.com/espressif/esp-idf/commit/1e07f6d83ca892630a7210df2958455f7ca77b4ahttps://github.com/espressif/esp-idf/commit/5731c63ece128f156939b9f734256e2227c1442ahttps://github.com/espressif/esp-idf/commit/8de265dc44b1b22c749ea44ee7c609b3da4162f0https://github.com/espressif/esp-idf/commit/9a6d04f65e0e341e7d72bd417c9f31b8a04ce846https://github.com/espressif/esp-idf/commit/c2610255a5adce651ca582bb82368c3dd0ee2834https://github.com/espressif/esp-idf/commit/c8cd8f4f3019ae2f912c8cbe9974445e8d9b8749https://github.com/espressif/esp-idf/releases/tag/v5.2.8https://github.com/espressif/esp-idf/releases/tag/v5.3.6https://github.com/espressif/esp-idf/releases/tag/v5.5.5https://github.com/espressif/esp-idf/releases/tag/v6.0.3https://github.com/espressif/esp-idf/releases/tag/v6.1-rc1#espressif #esp-idf#CVE_2026_81507#bot", "url": "https://infosec.exchange/users/cve/statuses/117434300245554962"}, {"timestamp": "2026-10-13T16:17:23.447Z", "date_only": false, "value": "2026-10-13T16:17:23.447", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-81507", "record": "FKIE_CVE-2026-81507", "field": "published"}, {"timestamp": "2026-10-14T15:00:21.832Z", "date_only": false, "value": "2026-10-14T15:00:21.832346Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-81507", "field": "containers.adp.0.metrics.0.other.content.timestamp"}, {"timestamp": "2026-10-14T15:00:21.832Z", "date_only": false, "value": "2026-10-14T15:00:21.832346Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-81507", "record": "FKIE_CVE-2026-81507", "field": "metrics.ssvcV203.0.ssvcData.timestamp"}, {"timestamp": "2026-10-14T15:00:34.785Z", "date_only": false, "value": "2026-10-14T15:00:34.785Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2026-81507", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-10-14T15:00:34.785Z", "date_only": false, "value": "2026-10-14T15:00:34.785Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-81507", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-10-14T15:17:25.750Z", "date_only": false, "value": "2026-10-14T15:17:25.750", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-81507", "record": "FKIE_CVE-2026-81507", "field": "lastModified"}]}
