In Audio HAL, there is a possible out of bounds write due to a heap buffer overflow. This could lead to local denial of service with User execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS10960023 (Note: For MT6880, MT6890, MT6980D, MT6988, MT6990) / AUTO00851189 (Note: For MT2735, MT3737); Issue ID: MSV-7586.
