Buffer Overflow Vulnerability in RIOT Operating System Could Lead to Denial of Service or Arbitrary Code Execution

CVE-2024-31225

What is CVE-2024-31225?

The RIOT operating system, which supports a variety of 8-bit, 16-bit, and 32-bit microcontrollers, contains a vulnerability in its _on_rd_init() function. This function is not equipped with adequate size checks for the _result_buf static buffer during data copying. If an attacker manages to craft a sufficiently long payload, this can lead to a buffer overflow. The implications of this vulnerability include the possibility of denial of service or arbitrary code execution, especially if attacker-controlled inputs traverse security boundaries. Currently, this vulnerability has not been addressed with a patch, and users are strongly encouraged to implement manual bounds checking to mitigate risks.
