CVE-2018-9483

Adjacent information disclosure via freed Bluetooth address

Published Nov 20, 2024 · Updated Nov 20, 2024

Use-after-free in Android 7.0 through 9 allows remote attackers to read Bluetooth-process memory over an adjacent connection. bta_dm_remove_sec_dev_entry passes a device-record-backed address to BTM_SecDeleteDevice, which frees that record, then reuses the invalid address for GATT cleanup; the patch copies the address before deletion. Bluetooth proximity is required, but no privileges or user interaction are needed, and the bounded consequence is memory disclosure rather than modification or service interruption.
