CVE-2026-37230

FlexRIC v2.0.0 crashes when the near-RT RIC receives a RICINDICATION message with a ranfuncid that does not exist in its registry. The lookup returns NULL, triggering assert in Debug builds SIGABRT or NULL pointer dereference in Release builds SIGSEGV. A remote unauthenticated attacker can crash...

FlexRIC v2.0.0 crashes when the near-RT RIC receives a RICINDICATION message with a ranfuncid that does not exist in its registry. The lookup returns NULL, triggering assert in Debug builds SIGABRT or NULL pointer dereference in Release builds SIGSEGV. A remote unauthenticated attacker can crash...

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-2026-37227

FlexRIC v2.0.0 contains reachable assert0 calls in stub message handlers for whitelisted but unimplemented E2AP message types in the near-RT RIC. A remote unauthenticated attacker can send a decodable E2AP PDU of such a type e.g., E2nodeConfigurationUpdate to crash the near-RT RIC process port...

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-2026-37221

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...

CVE-2026-37220

FlexRIC v2.0.0 crashes when an SCTP association is closed before an E2SETUPREQUEST is sent. The near-RT RIC assumes a mapping between SCTP association and E2 node always exists in the cleanup path and enforces this via assert. A remote unauthenticated attacker can crash the near-RT RIC port 36421...

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...

CVE-2026-37229

FlexRIC v2.0.0 contains a reachable assertion in e2apcreatepdu triggered when ASN.1 PER decoding fails. A remote unauthenticated attacker can send any non-PER byte sequence e.g., a single 0x00 byte over SCTP to the near-RT RIC port 36421 or iApp port 36422 to crash the process via SIGABRT. The...

CVE-2026-37229

CVE-2026-37229 affects FlexRIC v2.0.0. A reachable assertion in e2ap_create_pdu() is triggered when ASN.1 PER decoding fails, allowing a remote unauthenticated attacker to send a non-PER byte sequence (e.g., 0x00) over SCTP to the near-RT RIC at port 36421 or iApp at port 36422 to crash the proce...

CVE-2026-37233

CVE-2026-37233 affects FlexRIC v2.0.0. The iApp/xApp isolation contains an authorization bypass: the function eq_xapp_ric_gen_id() compares m0->xapp_id against itself rather than the other argument, effectively ignoring the xApp identity dimension. A malicious xApp connected to the iApp (port ...

EUVD-2026-33660

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...

FlexRIC security vulnerabilities
