Last modified Jun 17, 2026

CVE-2026-37234 is a high-severity vulnerability rated 8.2/10 on the CVSS scale. 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. EPSS estimates a 0.34% chance of exploitation in the next 30 days.

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.
