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...

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...

Mosaic5G FlexRIC 异常处理不当漏洞

FlexRIC is an open-source RAN intelligent controller developed by Mosaic5G. The FlexRIC v2.0.0 version contains a security vulnerability. This vulnerability stems from the use of the assert function to enforce the existence of pending events when processing RICSUBSCRIPTIONRESPONSE with an unknown...

openairinterface5G 安全漏洞

openairinterface5G is an open-source implementation of the OAI project, focusing on the research, development, and testing of 5G NR New Radio core networks and access networks. Version 2.4.0 of openairinterface5G contains a security vulnerability. This vulnerability stems from the E2SM-KPM RAN...

CVE-2026-37225

FlexRIC v2.0.0 is vulnerable to a denial-of-service (DoS) condition due to a cross-layer validation mismatch. The E42 layer decoder incorrectly accepts an E42_RIC_SUBSCRIPTION_REQUEST containing an empty ricEventTriggerDefinition field as valid. However, the E2AP encoder asserts a non-empty const...

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 arises from the fact that when the lookup function returns NULL, the assert function during debugging builds triggers a SIGABRT, or in release...

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-2026-37226

FlexRIC v2.0.0 crashes when the iApp receives an E42RICSUBSCRIPTIONREQUEST referencing a non-existent E2 Node. The lookup function returns NULL, which is enforced by assert in Debug builds SIGABRT and dereferenced in Release builds SIGSEGV. A remote unauthenticated attacker can crash the iApp...

CVE-2026-37226

The open-source RAN intelligent controller FlexRIC v2.0.0 is vulnerable to a crash in the iApp process (port 36422). A remote unauthenticated attacker can trigger this crash by sending an E42_RIC_SUBSCRIPTION_REQUEST that references a non-existent E2 Node using an arbitrary global_e2_node_id . Th...

CVE-2026-37233

FlexRIC v2.0.0 contains an authorization bypass within the iApp's xApp isolation mechanism. The root cause is a logical error in the eq_xapp_ric_gen_id() function located in src/ric/iApp/xapp_ric_id.c, where the code compares m0->xapp_id against itself rather than the required argument m1->...

CVE-2026-37221

FlexRIC v2.0.0 crashes when receiving a RICSUBSCRIPTIONRESPONSE with an unknown ricid that has no corresponding pending event. The near-RT RIC uses assert to enforce the existence of a pending event during response processing. A remote unauthenticated attacker can send a forged...

PT-2026-45506

Name of the Vulnerable Software and Affected Versions FlexRIC version 2.0.0 Description A remote unauthenticated attacker can cause the iApp process on port 36422 to crash by sending an E42 RIC SUBSCRIPTION REQUEST that references a non-existent E2 Node. This occurs because the lookup function...

Name of the Vulnerable Software and Affected Versions FlexRIC version 2.0.0 Description A flaw allows a single SCTP connection to bind multiple xapp ids by sending multiple E42 SETUP REQUESTs. Upon disconnection, the system only cleans up resources for the first registered xapp id, leaving...

CVE-2026-37232

An issue was discovered in OpenAirInterface5G 2.4.0 nr-softmodem in the E2SM-KPM RAN Function's PRB utilization metric calculation. The functions fillRRUPrbTotDl and fillRRUPrbTotUl in openair2/E2AP/RANFUNCTION/O-RAN/ranfunckpmsubs.c lines 182 and 197 compute PRB usage percentages by dividing by...
