{"id":"CVE-2026-28526","summary":"BlueKitchen BTstack \u003c 1.8.1 AVRCP Controller LIST_PLAYER_APPLICATION_SETTING_* Handlers OOB Read","details":"BlueKitchen BTstack versions prior to 1.8.1 contain an out-of-bounds read vulnerability in the AVRCP Controller LIST_PLAYER_APPLICATION_SETTING_ATTRIBUTES and LIST_PLAYER_APPLICATION_SETTING_VALUES handlers that allows attackers to read beyond buffer boundaries. A nearby attacker with a paired Bluetooth Classic connection can send a specially crafted VENDOR_DEPENDENT response with an attacker-controlled count value to trigger an out-of-bounds read from the L2CAP receive buffer, potentially causing a crash on resource-constrained devices.","modified":"2026-08-07T11:48:53.233820564Z","published":"2026-03-30T14:06:55.599Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/28xxx/CVE-2026-28526.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-125"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/28xxx/CVE-2026-28526.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-28526"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/bluekitchen-btstack-avrcp-controller-list-player-application-setting-handlers-oob-read"},{"type":"FIX","url":"https://github.com/bluekitchen/btstack/releases/tag/v1.8.1"},{"type":"PACKAGE","url":"https://github.com/bluekitchen/btstack"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/bluekitchen/btstack","events":[{"introduced":"0"},{"fixed":"36519fc00c196925a87867e960a27e89b0406452"}],"database_specific":{"source":["AFFECTED_FIELD","CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:bluekitchen-gmbh:btstack:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"1.8.1"}]}}],"versions":["v1.8","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-2026-28526.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:P/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N"}]}
