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-2026-37221

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...

EUVD-2026-33698

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-2026-37227

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-2026-37224

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-2026-37221

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-2026-45509

FlexRIC v2.0.0 crashes when the near-RT RIC receives a RIC INDICATION message with a ran func id 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 cra...

CVE-2026-37222

FlexRIC v2.0.0 uses hardcoded assertions to validate Information Element IE counts in decoded E2AP messages. A remote unauthenticated attacker can send a valid E2AP PDU containing an unexpected number of IEs e.g., an E2setupRequest with extra optional fields to crash the near-RT RIC port 36421 or...

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-2026-45430

FlexRIC v2.0.0 crashes when an SCTP association is closed before an E2 SETUP REQUEST 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 364...

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...

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...

CVE-2026-37220

FlexRIC v2.0.0 crashes when an SCTP association is closed before an E2SETUPREQUEST is sent.

A remote unauthenticated attacker can crash the near-RT RIC port 36421...

CVE-2026-37224

Summary: FlexRIC v2.0.0 crashes when it receives two identical E2_SETUP_REQUEST messages from the same or spoofed E2 Nodes. The iApp registry enforces node ID uniqueness via an assert(), not a graceful rejection, leading to a remote unauthenticated crash of the iApp process (port 36421) and a SIG...

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-2026-37221

FlexRIC v2.0.0 is affected. Processing a RIC_SUBSCRIPTION_RESPONSE with an unknown ric_id that has no corresponding pending event can trigger an assertion failure (near-RT RIC) leading to SIGABRT in Debug builds or a NULL pointer dereference (SIGSEGV) in Release builds. This can be exploited remo...

CVE-2026-37227

FlexRIC v2.0.0 is affected by a crash-inducing flaw in near-RT RIC E2AP handlers. Reachable assert(0) calls exist in stub handlers for whitelisted but unimplemented E2AP message types (e.g., E2nodeConfigurationUpdate). A remote unauthenticated attacker can send a decodable E2AP PDU of such a type...

CVE-2026-37222

FlexRIC v2.0.0 contains a vulnerability where the stack asserts exact Information Element (IE) counts in decoded E2AP messages instead of validating against protocol ranges. An unauthenticated remote attacker can send a valid E2AP PDU (for example, an E2setupRequest with extra optional fields) th...

PT-2026-45508

FlexRIC v2.0.0 contains a reachable assertion in e2ap create pdu 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...
