CVE-2026-37223

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-2026-37222

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-2026-45453

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-2026-37220

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-2026-37224

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...

EUVD-2026-33659

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-2026-37226

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-2026-37229

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...

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 stems from the assertion in the e2aprecvsctpmsg function, where assertrc len is used. This could allow unauthorized remote attackers to send SCT...

FlexRIC 安全漏洞

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 an authorization bypass in the iApp’s xApp isolation mechanism. The comparison function incorrectly compares xappid with itself...

Mosaic5G flexric 异常处理不当漏洞

FlexRIC is an open-source RAN intelligent controller developed by Mosaic5G. Version FlexRIC v2.0.0 contains a security vulnerability. This vulnerability stems from the iApp message distributor using assert for validation of the allowlist, which may allow remote unauthenticated attackers to send...

Mosaic5G flexric 异常处理不当漏洞

FlexRIC is an open-source RAN intelligent controller developed by Mosaic5G. Version FlexRIC v2.0.0 contains a security vulnerability. This vulnerability stems from a mismatch in cross-layer verifications: the E42 layer accepts an empty ricEventTriggerDefinition field, while the E2AP encoder asser...

FlexRIC 安全漏洞

FlexRIC is an open-source RAN intelligent controller developed by Mosaic5G. The FlexRIC v2.0.0 version contains a security vulnerability. This vulnerability arises from the fact that a single SCTP connection can be bound to multiple xappids, but only the first registered resource is cleaned up wh...

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-2026-37224

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-2026-37231

FlexRIC v2.0.0 uses a uint16t counter for xappid assignment but stores the value in uint32t message fields. After 65,530+ E42SETUPREQUESTs, the 16-bit counter wraps around and produces duplicate xappids. The iApp port 36422 crashes when attempting to register a duplicate ID in its internal data...

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...
