A bonded peer can send an AVDTP DISCOVER response with more endpoints than the fixed table holds, causing out-of-bounds writes that corrupt adjacent static objects and crash the process or sever event delivery.","modified":"2026-09-19T08:01:25.032815Z","published":"2026-09-17T15:16:52.858Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-1284","CWE-787"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93015.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93015.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93015"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/bluekitchen-btstack-through-1.8.2-a2dp-sep-discovery-out-of-bounds-write"},{"type":"FIX","url":"https://github.com/bluekitchen/btstack/commit/fc208fcce056d4e0a5bb916abc90e83a383e1cdf"},{"type":"PACKAGE","url":"https://github.com/bluekitchen/btstack"},{"type":"ARTICLE","url":"https://github.com/bluekitchen/btstack/blob/v1.8.2/src/classic/a2dp.c#L568"},{"type":"ARTICLE","url":"https://github.com/bluekitchen/btstack/blob/v1.8.2/src/classic/avdtp.c#L1703"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/bluekitchen/btstack","events":[{"introduced":"0"},{"fixed":"075a0780f0fad7ff67d58ac19f46e8953656a752"},{"fixed":"fc208fcce056d4e0a5bb916abc90e83a383e1cdf"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.8.2"}],"source":["DESCRIPTION","REFERENCES"]}}],"versions":["v1.8.1","v1.8","v1.7-rc1","v1.6.2","v1.6.1","v1.6","v1.5.6.3","v1.5.6.2","v1.5.6.1","v1.5.6","v1.5.5","v1.5.4","v1.5.3","v1.5.2","v1.5.1","v1.4.1","v1.4","v1.3.2","v1.3","v1.2.1","v1.2","v1.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93015.json","vanir_signatures_modified":"2026-09-19T08:01:25Z","vanir_signatures":[{"signature_type":"Function","signature_version":"v1","source":"https://github.com/bluekitchen/btstack/commit/fc208fcce056d4e0a5bb916abc90e83a383e1cdf","target":{"file":"src/classic/a2dp.c","function":"a2dp_config_process_avdtp_event_handler"},"deprecated":false,"digest":{"function_hash":"166695304071514374471177529250567602061","length":14268},"id":"CVE-2026-93015-1fc7ca50"},{"digest":{"line_hashes":["310377897356800949311904586491867244428","40817128634803920279671729268007105340","223445841734866609812216159172401028817","35260116276574606428978209869209251207"],"threshold":0.9},"id":"CVE-2026-93015-e066a00c","signature_type":"Line","signature_version":"v1","source":"https://github.com/bluekitchen/btstack/commit/fc208fcce056d4e0a5bb916abc90e83a383e1cdf","target":{"file":"src/classic/a2dp.c"},"deprecated":false}]}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N"}]}
