7.5 · HIGH

FlexRIC v2.0.0 uses hardcoded assertions to validate Information Element (IE) counts in decoded E2AP messages.

Published Jun 1, 2026CWE-617EPSS 0.61%

Overview

CVE-2026-37222 is a high-severity vulnerability. It was published on June 1, 2026 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

FlexRIC v2.0.0 uses hardcoded assertions to validate Information Element (IE) counts in decoded E2AP messages. A remote unauthenticated attacker can send a valid E2AP PDU containing an unexpected number of IEs (e.g., an E2setupRequest with extra optional fields) to crash the near-RT RIC (port 36421) or iApp (port 36422) via SIGABRT. The code asserts exact IE counts rather than validating against protocol-specified ranges.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
