In rw_t4t_sm_read_ndef of rw_t4t in Android 7.1.1, 7.1.2, 8.0, 8.1 and 9, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege in the NFC service with no additional execution privileges needed. User interaction is not needed for exploitation.
The product writes data past the end, or before the beginning, of the intended buffer.
