CVE-2026-45182

GrapheneOS before 2026050400 allows attackers to discover the real IP address of a VPN user as a consequence of a registerQuicConnectionClosePayload optimization, because an application can let system_server transmit UDP traffic on its behalf. This occurs when the "Block connections without VPN" and "Always-on VPN" settings are enabled.
