CVE-2024-52802

RIOT-OS missing dhcpv6_opt_t minimum header length check

RIOT is an operating system for internet of things (IoT) devices. In version 2024.04 and prior, the function parseadvertise, located in /sys/net/application_layer/dhcpv6/client.c, has no minimum header length check for dhcpv6optt after processing dhcpv6msgt. 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 preparseadvertise, which is called by parseadvertise before handling the request. As of time of publication, no known patched version exists.
