CVE-2026-38719 is a medium-severity vulnerability rated 6.2/10 on the CVSS scale. OpENer v2.3-558-g1e99582 contains an out-of-bounds read vulnerability in the Common Packet Format (CPF) parser, specifically in CreateCommonPacketFormatStructure() in source/src/enet_encap/cpf.c. A crafted ENIP/CPF message can supply an attacker-controlled item_count value that is not consistently validated against the remaining data_length of the CPF slice. EPSS estimates a 0.11% chance of exploitation in the next 30 days.
