Permission bypass vulnerability in the calendar storage module
Impact: Successful exploitation of this vulnerability may affect the schedule reminder function of head units.

CVE-2025-53178 is a medium-severity permission bypass vulnerability identified in Huawei's HarmonyOS, specifically affecting the calendar storage module in versions 4.0.0, 4.2.0, and 4.3.0. The vulnerability is categorized under CWE-264, which relates to improper permissions, privileges, and access controls. This flaw allows an attacker with limited privileges (PR:L) and requiring user interaction (UI:R) to bypass intended permission checks within the calendar storage component. The attack vector is local (AV:L), meaning the attacker must have local access to the device or system running HarmonyOS. Successful exploitation could compromise the confidentiality, integrity, and availability of the schedule reminder function on head units, which are typically embedded systems used in automotive infotainment or other integrated environments. The CVSS v3.1 base score is 4.8, reflecting a medium impact with low complexity but requiring some privileges and user interaction. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability could allow unauthorized modification or suppression of calendar reminders, potentially disrupting critical scheduling functions or enabling further attacks through manipulation of time-based events or notifications within the system.
