In 5.5.5, 6.0.1, and 6.1, the BlueDroid A2DP sink function btc_a2dp_sink_handle_inc_media() reads a timestamp field from the received media buffer before validating that the packet layout contains the field. A paired BR/EDR audio source within radio range can send a malformed A2DP media packet to a build with BlueDroid Classic Bluetooth and A2DP sink support enabled, causing an out-of-bounds read into adjacent heap memory and limited disclosure of heap contents. Arbitrary memory disclosure and code execution are not established.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":4.3},"cwes":["CWE-125"],"references":["https://github.com/espressif/esp-idf/commit/0d118139ff8b7aa87b656c2f4a6421ecaa1f5939","https://github.com/espressif/esp-idf/commit/6cb20db4dfeee81314d0c55acb82f3f0e7679abe","https://github.com/espressif/esp-idf/commit/85d56bcd266117e0fe6a6b75511c8e122fda29ad","https://github.com/espressif/esp-idf/commit/ca55d63de82e41e2c672bfd2b707fc80911f30ce","https://github.com/espressif/esp-idf/security/advisories/GHSA-xcpr-5mqp-9qvv"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-81508","score":0.00213,"percentile":0.11598,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
