PDF preview crash via null pointer dereference

Published Jul 7, 2025 · Updated Jul 7, 2025

Null pointer dereference in Huawei HarmonyOS 5.0.1 and 5.1.0 allows remote attackers to crash PDF preview processing after user interaction. The PDF preview module dereferences a null pointer, but Huawei has not disclosed the affected function, crafted PDF property, or erroneous operation. Exploitation requires interaction with attacker-supplied content and causes a service interruption, with no reported data exposure or modification.
