Service interruption via LBS permission bypass
Published Apr 13, 2026 · Updated Apr 13, 2026
Permission bypass in the LBS module in affected Huawei EMUI and HarmonyOS versions allows attackers to interrupt service. Huawei has not published the affected code path or the incorrect permission operation performed on untrusted input. Exploitation requires a local, highly privileged attacker and user interaction; the exact form and duration of service interruption are undisclosed.
