CVE-2026-37234 Details
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.

This issue arises because a single SCTP connection can bind multiple xapp_ids by sending multiple E42_SETUP_REQUEST messages. When the connection is disconnected, only the resources for the first registered xapp_id are cleaned up, leaving the subsequent xapp_ids and their associated subscriptions as stale entries.
