In tscpu_write_GPIO_out and mtkts_Abts_write of mtk_ts_Abts.c, there is a possible buffer overflow in an sscanf due to improper input validation. This could lead to a local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
