## Overview

Open5GS through 2.8.0 contains a heap out-of-bounds read vulnerability in ogs_pfcp_parse_volume_measurement() in lib/pfcp/types.c that allows remote unauthenticated attackers to read past IE buffers. Attackers can send a PFCP Session Report Request to the SMF on UDP port 8805 with a short, all-flags Volume Measurement IE, reading up to 48 bytes and potentially crashing the SMF.
