(CVE-2026-71217)\nUnbounded peer-controlled allocation in iperf3 json_read() allows\nunauthenticated remote memory exhaustion. (CVE-2026-71218)\nIperf3 3.21 (esnet/iperf) contains a remote, unauthenticated heap\nuse-after-free: the server's per-test watchdog server_timer_proc() frees\nstreams without cancelling/joining their worker threads, so a blocked\nworker dereferences a freed iperf_stream. (CVE-2026-101276)\nIperf3 3.20–3.21 (esnet/iperf) has a pre-auth heap buffer overflow in\ndecrypt_rsa_message(): a 256-byte RSA buffer is BIO_read with the\nattacker-controlled ciphertext length (guard warns only), so an\nunauthenticated client overflows the heap via an oversized authtoken.\n(CVE-2026-101283)\nIperf3 < 3.22 UDP Receive Worker Infinite Loop DoS.
