Remote memory disclosure via short MIFARE response
Published Jun 15, 2022 · Updated Aug 3, 2024
Out-of-bounds read in Android 10 through 12L allows remote attackers to disclose process memory through a crafted NFC MIFARE response. phNciNfc_RecvMfResp in phNxpExtns_MifareStd.cpp reads the response identifier and status without first ensuring the buffer contains two bytes. No privileges or user interaction are required, but exploitation depends on reaching the NFC MIFARE response path; the bounded impact is remote memory disclosure.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
