{"cve":"CVE-2024-31225","nvd":{"published":"2024-05-01T07:15:38.977","modified":"2026-06-17T07:28:00.933","status":"Analyzed","description":"RIOT is a real-time multi-threading operating system that supports a range of devices that are typically 8-bit, 16-bit and 32-bit microcontrollers. The `_on_rd_init()` function does not implement a size check before copying data to the `_result_buf` static buffer. If an attacker can craft a long enough payload, they could cause a buffer overflow. If the unchecked input above is attacker-controlled and crosses a security boundary, the impact of the buffer overflow vulnerability could range from denial of service to arbitrary code execution. This issue has yet to be patched. Users are advised to add manual bounds checking.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H","score":9.0},"cwes":["CWE-120"],"references":["http://seclists.org/fulldisclosure/2024/May/7","http://www.openwall.com/lists/oss-security/2024/05/07/3","https://github.com/RIOT-OS/RIOT/blob/master/sys/net/application_layer/cord/lc/cord_lc.c#L218","https://github.com/RIOT-OS/RIOT/security/advisories/GHSA-2572-7q7c-3965","http://seclists.org/fulldisclosure/2024/May/7"],"products":["riot-os:riot"],"source":"nvd","synced_at":"2026-10-19T21:49:08.435428910+00:00"},"epss":{"cve":"CVE-2024-31225","score":0.01301,"percentile":0.70473,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
