A stack-based buffer overflow vulnerability exists in the Bosch Sensortec BHI385 SensorAPI (C library) within the debug message parser function bhi385_parse_debug_message (located in bhi385_parse.c). <\/p>\n
The function parses FIFO events and extracts an 8-bit message length directly from the attacker-controlled event payload (callback_info->data_ptr[0]) without enforcing bounds checks or clamping the value.<\/p>\n
When copying the payload into a fixed-size stack buffer of 17 bytes (uint8_t debug_msg[17]) via memcpy, providing a length byte greater than 16 causes the function to write past the allocated stack boundary. <\/p>\n
This memory corruption can be triggered by a malicious or compromised sensor or bus participant, leading to a firmware crash, Denial of Service (DoS), or potentially the execution of arbitrary code via adjacent stack data corruption.<\/p>\n","protected":false},"excerpt":{"rendered":"
