CVE-2026-37234 | BDVDB-2026-337038 Detail

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.

Impact#

Per CVSS v3.1: confidentiality impact none, integrity impact low, availability impact high. Attack vector: network.
