Jun 1, 2026FlexRIC v2.0.0 allows a single SCTP connection to bind multiple xapp_ids by sending multiple E42_SETUP_REQUESTs.CVE-2026-37234 · Other software · Mosaic5g · reported by MITREHigh 8.2
FlexRIC v2.0.0 allows a single SCTP connection to bind multiple xapp_ids by sending multiple E42_SETUP_REQUESTs. On disconnect, only the first registered xapp_id's resources are cleaned up; subsequent xapp_ids and their subscriptions remain as stale entries. A remote attacker can exploit this to leak subscription state in the iApp, potentially causing resource exhaustion or state corruption over time.

Jun 1, 2026FlexRIC v2.0.0 trusts the xapp_id field from E42 message payloads without binding it to the sender's SCTP association.CVE-2026-37235 · Other software · Mosaic5g · reported by MITREHigh 7.5
FlexRIC v2.0.0 trusts the xapp_id field from E42 message payloads without binding it to the sender's SCTP association. The validation function valid_xapp_id() only checks that the value is within the assigned range. A remote unauthenticated attacker can impersonate any xApp by specifying their xapp_id in requests sent to the iApp (port 36422), causing responses to be misrouted to the victim xApp. This can crash the victim xApp, the RIC, or the iApp itself through state inconsistencies in the red-black tree data structure.

Jun 1, 2026FlexRIC v2.0.0 contains an authorization bypass in the iApp's xApp isolation mechanism.CVE-2026-37233 · Other software · Mosaic5g · reported by MITREHigh 7.5
FlexRIC v2.0.0 contains an authorization bypass in the iApp's xApp isolation mechanism. The equality function eq_xapp_ric_gen_id() in src/ric/iApp/xapp_ric_id.c compares m0->xapp_id against itself (m0->xapp_id) instead of the other argument (m1->xapp_id), effectively ignoring the xApp identity dimension. A malicious xApp connected to the iApp (port 36422) can delete any other xApp's subscriptions by sending an E42_RIC_SUBSCRIPTION_DELETE_REQUEST with a matching ric_gen_id. This breaks multi-tenant isolation in any deployment with multiple xApps sharing the same RIC.

Jun 1, 2026FlexRIC v2.0.0 uses a uint16_t counter for xapp_id assignment but stores the value in uint32_t message fields.CVE-2026-37231 · Other software · Mosaic5g · reported by MITREHigh 7.5
FlexRIC v2.0.0 uses a uint16_t counter for xapp_id assignment but stores the value in uint32_t message fields. After 65,530+ E42_SETUP_REQUESTs, the 16-bit counter wraps around and produces duplicate xapp_ids. The iApp (port 36422) crashes when attempting to register a duplicate ID in its internal data structure. A remote attacker can trigger this by repeatedly connecting and requesting new xApp registrations.

Jun 1, 2026FlexRIC 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.CVE-2026-37230 · Other software · Mosaic5g · reported by MITREHigh 7.5
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 crash the near-RT RIC (port 36421) by sending a crafted RIC_INDICATION with an arbitrary ran_func_id value.

Jun 1, 2026FlexRIC v2.0.0 contains a reachable assertion in e2ap_create_pdu() triggered when ASN.1 PER decoding fails.CVE-2026-37229 · Other software · Mosaic5g · reported by MITREHigh 7.5
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 assertion is reached before any protocol-level validation occurs. All three E2AP protocol versions (v1.01, v2.03, v3.01) are affected.

Jun 1, 2026FlexRIC v2.0.0 contains a reachable assertion in e2ap_recv_sctp_msg() (src/lib/ep/e2ap_ep.c).CVE-2026-37228 · Other software · Mosaic5g · reported by MITREHigh 7.5
FlexRIC v2.0.0 contains a reachable assertion in e2ap_recv_sctp_msg() (src/lib/ep/e2ap_ep.c). The function allocates a fixed 32KB receive buffer and enforces assert(rc < len) on the sctp_recvmsg() return value. A remote unauthenticated attacker can send a single SCTP message with payload >= 32,768 bytes to crash the near-RT RIC, iApp, E2 Agent, or xApp process via SIGABRT. No valid E2AP PDU is required. All four SCTP endpoint types (ports 36421 and 36422) share this vulnerable code path. In Release builds (NDEBUG), the stripped assertion leads to a signed-to-unsigned integer overflow and potential out-of-bounds read.

Jun 1, 2026FlexRIC v2.0.0 crashes when the iApp receives an E42_RIC_SUBSCRIPTION_REQUEST referencing a non-existent E2 Node.CVE-2026-37226 · Other software · Mosaic5g · reported by MITREHigh 7.5
FlexRIC v2.0.0 crashes when the iApp receives an E42_RIC_SUBSCRIPTION_REQUEST 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 process (port 36422) by sending a subscription request with an arbitrary global_e2_node_id.

FlexRIC v2.0.0 contains reachable assert(0) 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 36421) via SIGABRT. The message passes whitelist validation but triggers an unconditional assertion in the handler.

FlexRIC v2.0.0 crashes when the iApp receives an E42_RIC_SUBSCRIPTION_REQUEST 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 iApp process (port 36422) via SIGABRT by exploiting this cross-layer validation mismatch.

Jun 1, 2026FlexRIC v2.0.0 crashes when receiving a duplicate E2_SETUP_REQUEST from the same or spoofed E2 Node.CVE-2026-37224 · Other software · reported by MITREHigh 7.5
FlexRIC v2.0.0 crashes when receiving a duplicate E2_SETUP_REQUEST 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 E2_SETUP_REQUESTs with the same E2 node configuration, triggering SIGABRT.

Jun 1, 2026FlexRIC v2.0.0 contains a reachable assertion in the iApp message dispatcher.CVE-2026-37223 · Other software · reported by MITREHigh 7.5
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 process (port 36422) via SIGABRT. Since iApp and the near-RT RIC share one process, this terminates the entire RIC service and disconnects all E2 Nodes and xApps.

Jun 1, 2026FlexRIC v2.0.0 uses hardcoded assertions to validate Information Element (IE) counts in decoded E2AP messages.CVE-2026-37222 · Other software · reported by MITREHigh 7.5
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 iApp (port 36422) via SIGABRT. The code asserts exact IE counts rather than validating against protocol-specified ranges.

FlexRIC v2.0.0 crashes when receiving a RIC_SUBSCRIPTION_RESPONSE with an unknown ric_id 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 RIC_SUBSCRIPTION_RESPONSE to the near-RT RIC (port 36421) to cause SIGABRT in Debug builds or NULL pointer dereference (SIGSEGV) in Release builds.

Jun 1, 2026FlexRIC v2.0.0 crashes when an SCTP association is closed before an E2_SETUP_REQUEST is sent.CVE-2026-37220 · Other software · reported by MITREHigh 7.5
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 36421) by simply completing an SCTP handshake and immediately disconnecting, without sending any E2AP message.
