CVE-2022-38993Network attack vector

Service interruption via undisclosed secure OS configuration

Published Sep 16, 2022 · Updated Aug 3, 2024

Configuration defects in Huawei HarmonyOS 2.0 and 2.1 and EMUI 12.0.0 allow remote attackers to interrupt system availability. Huawei identifies the locus only as the secure OS module and has not disclosed which configuration is defective or how attacker-controlled input reaches it. The published assessment indicates unauthenticated network reachability without user interaction, but public records do not distinguish a crash, hang, reboot, or other interruption.
