CVE-2023-7265

Local service interruption via undisclosed permission check

Published Aug 8, 2024 · Updated Aug 8, 2024

Improper permission verification in Huawei HarmonyOS and EMUI lock screen modules allows local users to interrupt device availability. Huawei has not disclosed the permission check, rejected operation, input, or resulting failure mode, so the specific mechanism remains unavailable. Exploitation requires local access, needs no prior privileges or user interaction, and has no reported confidentiality or integrity impact.
