Overview

CVE-2026-37234 is a high-severity vulnerability. It was published on June 1, 2026 and has a CVSS 3.1 base score of 8.2 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.2, 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 allows a single SCTP connection to bind multiple xapp_ids by sending multiple E42_SETUP_REQUESTs. On disconnect, only the first registered xapp_id's resources are cleaned up; subsequent xapp_ids and their subscriptions remain as stale entries. A remote attacker can exploit this to leak subscription state in the iApp, potentially causing resource exhaustion or state corruption over time.

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.
