Remote information disclosure via zero-length tag response
Published Jun 11, 2020 · Updated Aug 4, 2024
Out-of-bounds read in Android 10 NFC code allows remote attackers to disclose process memory through a crafted ISO 15693 tag response. The rw_i93_sm_detect_ndef function dereferences the response buffer when its length is zero instead of rejecting the invalid NFC tag data. Exploitation requires an attacker-controlled ISO 15693 tag response, needs no privileges or user interaction, and exposes memory without enabling modification or service interruption.
