CVE-2022-29794Network attack vector

Data compromise via frame scheduling use-after-free

Published May 13, 2022 · Updated Aug 3, 2024

A use-after-free in Huawei HarmonyOS 2.0 and EMUI 12.0.0 lets remote attackers affect data integrity, availability, and confidentiality. The frame scheduling module accesses an object after it has been released, creating a use-after-free condition. Network reachability and unauthenticated access are reflected in the published CVSS assessment, while Huawei provides no more specific triggering sequence or exploit precondition.
