CVE-2022-39004Network attack vector

Service interruption via MPTCP memory leak

Published Sep 16, 2022 · Updated Aug 3, 2024

Memory leakage in Huawei HarmonyOS and EMUI allows remote attackers to exhaust device memory through the MPTCP module. Huawei identifies an unreleased-memory condition in MPTCP but has not disclosed the affected code path or the input that leaves allocations live. No privileges or user interaction are required; repeated triggering can deplete memory and interrupt service without reported data disclosure or modification.
