CVE-2025-48905Network attack vector

Failure to capture specific Wasm exceptions

Published Jun 6, 2025 · Updated Jun 9, 2025

Wasm exception-capture inconsistency in Huawei HarmonyOS 5.0.0 allows remote attackers to bypass handling of specific exceptions. The ArkWeb V8 module fails to capture specific Wasm exception types, but Huawei has not disclosed the erroneous operation or crafted input. The network path requires no privileges or user interaction but has high attack complexity; Huawei has not specified the downstream consequence.
