Vulnerability in N/a

CVE-2026-37223

FlexRIC v2.0.0 contains a reachable assertion in the iApp message dispatcher. The dispatcher validates incoming E2AP messages against a 9-entry whitelist using assert(). A remote unauthenticated attacker can send any decodable E2AP PDU with a message type not in the whitelist to crash the iApp process (port 36422) via SIGABRT. Since iApp and the near-RT RIC share one process, this terminates the entire RIC service and disconnects all E2 Nodes and xApps.
