    CVE-2026-93015 (GCVE-0-2026-93015)

    Vulnerability from nvd – Published: 2026-09-17 15:16 – Updated: 2026-09-17 19:19
    VLAI
    Title
    BlueKitchen BTstack through 1.8.2 A2DP SEP Discovery Out-of-Bounds Write
    Summary
    BlueKitchen BTstack through 1.8.2 fails to validate the peer-reported endpoint count against table bounds in A2DP stream endpoint discovery. 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.

    Title
    BlueKitchen BTstack < 1.8.1 AVRCP Browsing Target GET_FOLDER_ITEMS Handler OOB Read / Undefined Behavior
    Summary
    BlueKitchen BTstack versions prior to 1.8.1 contain an out-of-bounds read vulnerability in the AVRCP Browsing Target GET_FOLDER_ITEMS handler that fails to validate packet boundaries and attribute count data. An attacker with a paired Bluetooth Classic connection can exploit insufficient bounds checking on the attr_id parameter to cause crashes and corrupt attribute bitmap state.

    CVE-2026-28527 (GCVE-0-2026-28527)

    Vulnerability from nvd – Published: 2026-03-30 14:07 – Updated: 2026-07-14 18:39 X_Open Source

    Title
    BlueKitchen BTstack < 1.8.1 AVRCP Controller GET_PLAYER_APPLICATION_SETTING_*_TEXT Handlers OOB Read
    Summary
    BlueKitchen BTstack versions prior to 1.8.1 contain an out-of-bounds read vulnerability in the AVRCP Controller GET_PLAYER_APPLICATION_SETTING_ATTRIBUTE_TEXT and GET_PLAYER_APPLICATION_SETTING_VALUE_TEXT handlers that allows nearby attackers to read beyond packet boundaries. Attackers can establish a paired Bluetooth Classic connection and send specially crafted VENDOR_DEPENDENT responses to trigger out-of-bounds reads, causing information disclosure and potential crashes on affected devices.

    CVE-2026-93015 (GCVE-0-2026-93015)

    Vulnerability from cvelistv5 – Published: 2026-09-17 15:16 – Updated: 2026-09-17 19:19

    Title
    BlueKitchen BTstack through 1.8.2 A2DP SEP Discovery Out-of-Bounds Write
    Summary
    BlueKitchen BTstack through 1.8.2 fails to validate the peer-reported endpoint count against table bounds in A2DP stream endpoint discovery. 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.

    Title
    BlueKitchen BTstack < 1.8.1 AVRCP Browsing Target GET_FOLDER_ITEMS Handler OOB Read / Undefined Behavior
    Summary
    BlueKitchen BTstack versions prior to 1.8.1 contain an out-of-bounds read vulnerability in the AVRCP Browsing Target GET_FOLDER_ITEMS handler that fails to validate packet boundaries and attribute count data. An attacker with a paired Bluetooth Classic connection can exploit insufficient bounds checking on the attr_id parameter to cause crashes and corrupt attribute bitmap state.

    Title
    BlueKitchen BTstack < 1.8.1 AVRCP Controller GET_PLAYER_APPLICATION_SETTING_*_TEXT Handlers OOB Read
    Summary
    BlueKitchen BTstack versions prior to 1.8.1 contain an out-of-bounds read vulnerability in the AVRCP Controller GET_PLAYER_APPLICATION_SETTING_ATTRIBUTE_TEXT and GET_PLAYER_APPLICATION_SETTING_VALUE_TEXT handlers that allows nearby attackers to read beyond packet boundaries. Attackers can establish a paired Bluetooth Classic connection and send specially crafted VENDOR_DEPENDENT responses to trigger out-of-bounds reads, causing information disclosure and potential crashes on affected devices.

    Title
    BlueKitchen BTstack < 1.8.1 AVRCP Controller LIST_PLAYER_APPLICATION_SETTING_* Handlers OOB Read
    Summary
    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.
