| CVE-2026-37234 | 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. | [email protected] | 8.2 | 0.15% | 2026-06-01 | 2026-06-05 |
| CVE-2026-37235 | 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 | [email protected] | 7.5 | 0.19% | 2026-06-01 | 2026-06-03 |
| CVE-2026-37233 | 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-tena | [email protected] | 7.5 | 0.05% | 2026-06-01 | 2026-06-03 |
| CVE-2026-37231 | 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. | [email protected] | 7.5 | 0.05% | 2026-06-01 | 2026-06-03 |
| CVE-2026-37230 | 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. | [email protected] | 7.5 | 0.18% | 2026-06-01 | 2026-06-03 |
| CVE-2026-37229 | 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. | [email protected] | 7.5 | 0.18% | 2026-06-01 | 2026-06-03 |
| CVE-2026-37228 | 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 Rele | [email protected] | 7.5 | 0.19% | 2026-06-01 | 2026-06-03 |
| CVE-2026-37226 | 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. | [email protected] | 7.5 | 0.27% | 2026-06-01 | 2026-06-03 |
