CVE-2026-37223_CVE-2026-37223

7.5 / 10

HIGH

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Description

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.
