CVE-2026-37231

Description
FlexRIC v2.0.0 uses a uint16_t counter for xapp_id assignment but stores the value in uint32_t message fields. After 65,530+ E42_SETUP_REQUESTs, the 16-bit counter wraps around and produces duplicate xapp_ids. The iApp (port 36422) crashes when attempting to register a duplicate ID in its internal data structure. A remote attacker can trigger this by repeatedly connecting and requesting new xApp registrations.
