CVE-2020-0165

Local privilege escalation via unchecked NFC buffer

Published Jun 11, 2020 · Updated Aug 4, 2024

Out-of-bounds write in Android 10's NXP NFC HAL allows local users with System privileges to escalate privilege through compromised firmware. phNxpNciHal_NfcDep_cmd_ext in phNxpNciHal_NfcDepSWPrio.cc writes beyond its intended buffer because it omits a bounds check. Exploitation requires already-compromised device firmware and System execution privileges, needs no user interaction, and can elevate local privilege.
