CVE-2018-9414

Local privilege escalation via oversized GATT response

Published Dec 2, 2024 · Updated Dec 3, 2024

Out-of-bounds stack write in Google Android 6.0 through 8.1 allows local users to escalate privileges via a Bluetooth GATT response. gattServerSendResponseNative in com_android_bluetooth_gatt.cpp copies an oversized server response without checking it against BTGATT_MAX_ATTR_LEN, overwriting stack memory. A malicious app needs User execution privileges, but no user interaction, and successful exploitation gains privileges in the Bluetooth process context.
