CVE-2018-9419Network attack vector

Remote information disclosure via unchecked L2CAP packet length

Published Nov 19, 2024 · Updated Nov 20, 2024

Out-of-bounds read in Android 7.0 through 8.1 allows remote attackers to disclose process memory via a crafted BLE L2CAP packet. The L2CAP_CMD_DISC_REQ branch in l2cble_process_sig_cmd reads two 16-bit channel identifiers without first confirming that four bytes remain in the signaling buffer. An unauthenticated nearby Bluetooth peer can trigger the read without user interaction, exposing memory contents but not enabling modification or code execution.
