CVE-2026-73215

CVE-2026-73215 affects Coturn (TURN/STUN server). Before 4.17.0, in turn_ports.c, turnports_allocate_even() marks an unused odd port as TPS_TAKEN_ODD for an EVEN-PORT Allocate with R=0, even though no RTCP socket will release it. An authenticated client can permanently exhaust the relay port pool...
