Technical ContextAI · show details

This vulnerability is classified under CWE-20. RIOT is an operating system for internet of things (IoT) devices. In version 2024.04 and prior, the function _parse_advertise, located in /sys/net/application_layer/dhcpv6/client.c, has no minimum header length check for dhcpv6_opt_t after processing dhcpv6_msg_t. This omission could lead to an out-of-bound read, causing system inconsistency. Additionally, the same lack of a header length check is present in the function _preparse_advertise, which is called by _parse_advertise before handling the request. As of time of publication, no known patched version exists. Affected products include: Riot-Os Riot. Version information: version 2024.04.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.
