CVE-2026-37225

FlexRIC v2.0.0 crashes when the iApp receives an E42RICSUBSCRIPTIONREQUEST with an empty ricEventTriggerDefinition field. The E42 layer decoder accepts this as valid, but the E2AP encoder asserts a non-empty constraint when forwarding the request. A remote unauthenticated attacker can crash the...

CVE-2026-37233

FlexRIC v2.0.0 contains an authorization bypass in the iApp's xApp isolation mechanism. The equality function eqxappricgenid in src/ric/iApp/xappricid.c compares m0-xappid against itself m0-xappid instead of the other argument m1-xappid, effectively ignoring the xApp identity dimension. A malicio...

CVE-2026-37231

FlexRIC v2.0.0 uses a uint16t counter for xappid assignment but stores the value in uint32t message fields. After 65,530+ E42SETUPREQUESTs, the 16-bit counter wraps around and produces duplicate xappids. The iApp port 36422 crashes when attempting to register a duplicate ID in its internal data...

EUVD-2026-33697

FlexRIC v2.0.0 contains a reachable assertion in the iApp message dispatcher. The dispatcher validates incoming E2AP messages against a 9-entry whitelist using assert. A remote unauthenticated attacker can send any decodable E2AP PDU with a message type not in the whitelist to crash the iApp...

CVE-2026-37224

FlexRIC v2.0.0 crashes when receiving a duplicate E2SETUPREQUEST from the same or spoofed E2 Node. The iApp registry enforces node ID uniqueness via assert rather than graceful rejection. A remote unauthenticated attacker can crash the iApp process port 36421 by sending two E2SETUPREQUESTs with t...

CVE-2026-37232

OpenAirInterface5G 2.4.0 (nr-softmodem) E2SM-KPM RAN Function PRB utilization calculation (fill_RRU_PrbTotDl/Ul in openair2/E2AP/RAN_FUNCTION/O-RAN/ran_func_kpm_subs.c) divides PRB difference by the previous total_prb_aggregate, missing a zero-check. If two consecutive samples are identical and a...

FlexRIC 安全漏洞

FlexRIC is an open-source RAN intelligent controller developed by Mosaic5G. Version FlexRIC v2.0.0 contains a security vulnerability. This vulnerability stems from the iApp message distributor using assert for validation of the allowlist, which may allow remote unauthenticated attackers to send...

CVE-2026-37235

FlexRIC v2.0.0 trusts the xappid field from E42 message payloads without binding it to the sender's SCTP association. The validation function validxappid only checks that the value is within the assigned range. A remote unauthenticated attacker can impersonate any xApp by specifying their xappid ...

CVE-2026-37235

FlexRIC v2.0.0 trusts the xapp_id field from E42 payloads without binding it to the sender’s SCTP association. The valid_xapp_id() check only ensures the value is within the assigned range, enabling a remote unauthenticated attacker to impersonate any xApp by supplying their xapp_id in requests t...

CVE-2026-37234

FlexRIC v2.0.0 allows a single SCTP connection to bind multiple xappids by sending multiple E42SETUPREQUESTs. On disconnect, only the first registered xappid's resources are cleaned up; subsequent xappids and their subscriptions remain as stale entries. A remote attacker can exploit this to leak...
