CVE-2026-37234: EURECOM FlexRIC resource leak via multiple xApp identity bindings

CVE-2026-37234 · Severity: info · CVSS 8.2 · Published 2026-06-01

EURECOM FlexRIC, a controller used in Open RAN cellular networks to manage radio resources, contains a flaw in how it handles connections from external applications (xApps). An attacker can repeatedly register multiple identities over a single connection, and when that connection is closed, the system fails to clean up all the associated data. Over time, this leads to a buildup of "stale" entries that can exhaust system memory or corrupt the controller's state, potentially disrupting cellular network operations.

Technical details

A resource management vulnerability exists in the FlexRIC iApp component due to improper handling of E42_SETUP_REQUEST messages. The function `e2ap_handle_e42_setup_request_iapp` in `msg_handler_iapp.c` fails to verify if an SCTP association already has an assigned xApp identity, allowing a single connection to bind multiple `xapp_id` values. Upon disconnection, the cleanup logic only identifies and removes the first registered `xapp_id`, leaving subsequent IDs and their associated subscription states as stale entries in memory. A remote, unauthenticated attacker can exploit this by sending multiple setup requests over one SCTP connection to port 36422, leading to uncontrolled resource consumption (CWE-400) and potential state corruption. As of the advisory date, no upstream patch is available.
