CVE-2026-37230

high

Description

FlexRIC v2.0.0 crashes when the near-RT RIC receives a RIC_INDICATION message with a ran_func_id that does not exist in its registry. The lookup returns NULL, triggering assert() in Debug builds (SIGABRT) or NULL pointer dereference in Release builds (SIGSEGV). A remote unauthenticated attacker can crash the near-RT RIC (port 36421) by sending a crafted RIC_INDICATION with an arbitrary ran_func_id value.
