CVE-2022-48512Network attack vector

Image-decoding disruption via Vdecoderservice use-after-free

Published Jul 6, 2023 · Updated Nov 19, 2024

Use-after-free in Huawei EMUI 12.0.0 and HarmonyOS 2.0.0 allows remote attackers to disrupt image decoding over a network. Vdecoderservice accesses heap memory after its lifetime ends, but Huawei has not disclosed the affected function or triggering input path. NVD reports that no privileges or user interaction are required; the documented consequence is abnormal image decoding, with no specific crash or hang reported.
