CVE-2024-52802 Information

Description

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.
