CVE-2017-18665

Memory corruption via WifiService adb-cmd

Published Apr 7, 2020 · Updated Aug 5, 2024

NULL pointer dereference in Samsung Android M(6.0) WifiService allows remote attackers to corrupt memory via an adb-cmd request. WifiService processes the adb-cmd input and dereferences a NULL pointer, corrupting memory instead of handling the invalid state safely. Exploitation requires access to the device's ADB command interface; observed impact is service instability or memory corruption, with no public evidence of code execution.
