CVE-2026-37233
FlexRIC v2.0.0 contains an authorization bypass in the iApp's xApp isolation mechanism. The equality function eqxappricgenid in src/ric/iApp/xappricid.c compares m0-xappid against itself m0-xappid instead of the other argument m1-xappid, effectively ignoring the xApp identity dimension. A malicio...
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...
EUVD-2026-33699
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...
EUVD-2026-33697
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-2026-37225
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-2026-37223
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-2026-37224
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-2026-37235
FlexRIC v2.0.0 trusts the xapp_id field from E42 payloads without binding it to the sender’s SCTP association. The valid_xapp_id() check only ensures the value is within the assigned range, enabling a remote unauthenticated attacker to impersonate any xApp by supplying their xapp_id in requests t...

CVE-2026-37235
FlexRIC v2.0.0 trusts the xappid field from E42 message payloads without binding it to the sender's SCTP association. The validation function validxappid only checks that the value is within the assigned range. A remote unauthenticated attacker can impersonate any xApp by specifying their xappid ...
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...
CVE-2026-37225
FlexRIC v2.0.0 is affected by CVE-2026-37225. The iApp crashes (SIGABRT) when processing an E42_RIC_SUBSCRIPTION_REQUEST that contains an empty ricEventTriggerDefinition field. The E42 layer decoder accepts the empty field, but the E2AP encoder enforces a non-empty constraint when forwarding the ...

CVE-2026-37226
FlexRIC v2.0.0 is vulnerable: when the iApp receives an E42_RIC_SUBSCRIPTION_REQUEST referencing a non-existent E2 Node, the lookup returns NULL and triggers an abort in Debug builds (SIGABRT) or a segfault in Release builds (SIGSEGV), allowing a remote unauthenticated attacker to crash the iApp ...

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...
