Service data exposure via futex permission bypass
Published Apr 7, 2025 · Updated Apr 7, 2025
Improper permission handling in Huawei HarmonyOS 5.0.0 allows local users to expose confidential service data through the kernel futex module. The futex module permits a memory write operation despite insufficient permissions, but Huawei has not disclosed the affected code path or attacker-controlled input. Exploitation requires local low-privileged access and no user interaction; the published impact is limited to service confidentiality.
