Description
ESF-IDF is the Espressif Internet of Things (IOT) Development Framework. In 5.5.1, 5.4.3, 5.3.4, 5.2.6, 5.1.6, and earlier, when AVRCP is enabled on ESP32, receiving a malformed VENDOR DEPENDENT command from a peer device can cause the Bluetooth stack to access memory before validating the command buffer length. This may lead to an out-of-bounds read, potentially exposing unintended memory content or causing unexpected behavior.
Affected configurations
• espressif esp-idf (<= 5.1.6)
• espressif esp-idf (>= 5.2 <= 5.2.6)
• espressif esp-idf (>= 5.3 <= 5.3.4)
• espressif esp-idf (>= 5.4 <= 5.4.3)
• espressif esp-idf (>= 5.5 <= 5.5.1)
