For Realtek AmebaD devices, a heap-based buffer overflow was discovered in Ameba-AIoT ameba-arduino-d before version 3.1.9 and ameba-rtos-d before commit c2bfd8216a1cbc19ad2ab5f48f372ecea756d67a on 2025/07/03. In the WLAN driver defragment function, lack of validation of the size of fragmented Wi-Fi frames may lead to a heap-based buffer overflow.
