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-2026-37226

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...

EUVD-2026-33700

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...

FlexRIC security vulnerabilities

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 security vulnerabilities

FlexRIC is an open-source RAN intelligent controller developed by Mosaic5G. Version FlexRIC v2.0.0 contains a security vulnerability. This vulnerability arises from the fact that when the lookup function returns NULL, the assert function during debugging builds triggers a SIGABRT, or in release...

FlexRIC security vulnerabilities

FlexRIC is an open-source RAN intelligent controller developed by Mosaic5G. Version FlexRIC v2.0.0 contains a security vulnerability. This vulnerability arises from the use of the assert function to enforce mapping relationships before sending the E2SETUPREQUEST message. This could allow remote...

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-2026-45453

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...

FlexRIC security vulnerabilities

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...

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-2026-37234

FlexRIC v2.0.0 allows a single SCTP connection to bind multiple xappids by sending multiple E42SETUPREQUESTs. On disconnect, only the first registered xappid's resources are cleaned up; subsequent xappids and their subscriptions remain as stale entries. A remote attacker can exploit this to leak...

FlexRIC security vulnerabilities

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 failure in ASN.1 PER decoding, resulting in a reachable assertion in e2apcreatepdu. This could allow unauthorized remote attackers ...

FlexRIC security vulnerabilities

FlexRIC is an open-source RAN intelligent controller developed by Mosaic5G. Version FlexRIC v2.0.0 contains a security vulnerability. This vulnerability arises from handling RICINDICATION messages that do not contain the ranfuncid field, causing an assert to be triggered or null pointer...

FlexRIC security vulnerabilities

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 trusting the xappid field in the trust E42 message without binding it to the sender’s SCTP association. As a result, remote...

CVE-2024-34034

An issue was discovered in FlexRIC 2.0.0. It crashes during a Subscription Request denial-of-service DoS attack, triggered by an assertion error. An attacker must send a high number of E42 Subscription Requests to the Near-RT RIC component...

FlexRIC 安全漏洞

FlexRIC is a RAN Intelligent Controller open-sourced by Mosaic5G. A security vulnerability exists in FlexRIC version 2.0.0 that stems from the presence of an assertion error that could lead to a denial of service DoS...
