CVE-2020-0157Network attack vector

Remote information disclosure via unchecked NFC HCI read

Published Jun 11, 2020 · Updated Aug 4, 2024

Out-of-bounds read in Android 10 NFC HCI handling allows remote attackers to disclose information through compromised device firmware. The nfa_hci_conn_cback callback in nfa_hci_main.cc fails to check bounds before reading HCI connection data, allowing a read beyond the intended buffer. Exploitation requires compromised device firmware executing with System privileges; no user interaction is required, and the bounded impact is information disclosure.
