Information disclosure via GPU resource reuse
Published Feb 18, 2024 · Updated Mar 27, 2025
Information disclosure in the GPU module of Huawei HarmonyOS 3.0.0, 3.1.0, and 4.0.0 and EMUI 13.0.0 allows remote attackers to read service data. Huawei describes resource reuse in the GPU module but has not disclosed which resource retains data or how an attacker causes its reuse. The published assessment requires no privileges or user interaction and limits the reported consequence to confidentiality loss.
