CVE-2018-9478Network attack vector

Remote code execution via unchecked SDP offsets

Published Nov 20, 2024 · Updated Nov 20, 2024

Out-of-bounds write in Android 7.0 through 9.0 allows remote attackers to execute arbitrary code via a crafted Bluetooth SDP request. The process_service_attr_req and process_service_search_attr_req handlers fail to validate continuation offsets before constructing partial attribute responses, allowing response-list writes beyond the allocated buffer. No authentication or user interaction is required, and successful exploitation permits arbitrary code execution on the device.
