CVE-2025-41067Network attack vector

NRF crash via self-registry deletion assertion

Published Oct 27, 2025 · Updated Oct 27, 2025

Reachable assertion in Open5GS 2.7.5 and earlier allows remote attackers with NRF connectivity to crash the NRF via an SBI request. A crafted SBI request deletes the NRF's own registry, after which a reachable check aborts the NRF process instead of rejecting the operation. NRF SBI network reachability is required; exploitation interrupts NF registration and discovery until the service restarts.
