EUVD-2026-33696

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...

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...

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...

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-2026-37227

The FlexRIC v2.0.0 software contains a vulnerability in the near-RT RIC component where stub message handlers for whitelisted but unimplemented E2AP message types contain reachable assert(0) calls. A remote unauthenticated attacker can exploit this by sending a decodable E2AP PDU (such as E2nodeC...

PT-2026-45456

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...

PT-2026-45507

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 assertrc = 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...

CVE-2026-37223

FlexRIC v2.0.0 is vulnerable to a service disruption due to a reachable assertion in the iApp message dispatcher . The dispatcher uses assert() to validate incoming E2AP messages against a 9-entry whitelist. A remote unauthenticated attacker can trigger a SIGABRT crash by sending a decodable E2AP...
