Availability interruption via undisclosed permission-check failure

Published Apr 7, 2024 · Updated Nov 18, 2024

A permission-check failure in the lock screen module of Huawei HarmonyOS and EMUI allows attackers to interrupt device availability. Neither Huawei advisory identifies the failed permission check or the operation performed on untrusted input. Affected releases are HarmonyOS 3.0.0, 3.1.0, and 4.0.0 and EMUI 12.0.0 and 13.0.0; Huawei has not disclosed the trigger or failure mode, while CISA assesses network reachability without privileges or user interaction.
