CVE-2022-48518

Malicious app autostart via delayed signature verification

Published Jul 6, 2023 · Updated Nov 19, 2024

Improper initialization in HarmonyOS 2.0.0 through 2.0.1 and EMUI 12.0.0 through 12.0.1 allows local users to autostart malicious apps. The iaware subsystem receives system broadcasts before its signature-verification state is initialized, so spoofed package names can match the startup trustlist without the intended signature check. Exploitation requires local user interaction with a malicious app; successful spoofing grants power-on execution and degrades system performance.
