CVE-2021-22430Network attack vector

Code injection via undisclosed logic bypass

Published Feb 25, 2022 · Updated Aug 3, 2024

Logic bypass in Huawei EMUI, Magic UI, and HarmonyOS releases allows attackers to inject code via an undisclosed vector. Huawei has not published the affected component, the input that reaches it, or the incorrect logic operation that accepts that input. The public record does not identify the required privileges, interaction, or execution context, so the consequence is bounded only as code injection on listed phone releases.
