Published Feb 6, 2026 · Updated Feb 6, 2026

Use-after-free in the graphics module of Huawei HarmonyOS 5.1.0 and 6.0.0 allows local users to cause an unspecified availability impact. During concurrent execution, the graphics module accesses an object after its lifetime ends; Huawei has not identified the object or triggering operation. Local access without prior privileges is required, but the resulting crash, hang, reboot, or other failure mode remains undisclosed.
