BlueKitchen BTstack < 1.8.1 AVRCP Controller LIST_PLAYER_APPLICATION_SETTING_* Handlers OOB Read

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.

跨界内存读

BTstack 安全漏洞

BTstack是BlueKitchen开源的一个蓝牙堆栈实现。 BTstack 1.8.1之前版本存在安全漏洞，该漏洞源于AVRCP控制器处理程序存在越界读取，可能导致崩溃。
