| Titel | uYanki board-stm32f103rc-berial 0.0 Buffer Overflow |
|---|
| Beschreibung | The function heartrate1_i2c_hal_write() contains a stack-based buffer overflow vulnerability (CWE-787). It copies num + 1 bytes of data into a fixed-size buffer buffer[MAX_READ_SIZE] without verifying if num + 1 exceeds the buffer's capacity. An attacker could exploit this by providing a large num value, leading to arbitrary code execution, system crash, or unauthorized access.
