Availability impairment via image codec null dereference

Published Aug 17, 2026 · Updated Aug 17, 2026

Null pointer dereference in Huawei HarmonyOS 6.1.0 allows local users to impair availability through the image codec module. The module dereferences a null pointer during an undisclosed image-processing operation, but Huawei has not identified the input, function, or trigger. Local access is required, and Huawei has not stated whether exploitation crashes a process, reboots a device, or causes another interruption.
