CVE-2026-37226

FAUCET Score

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.
