CVE-2020-0118

Local privilege escalation via remote Binder type confusion

Published Jun 10, 2020 · Updated Aug 4, 2024

Out-of-bounds write in Android 10 SurfaceFlinger allows local users to elevate privileges through a crafted region-sampling request. RegionSamplingThread::addListener casts an untrusted remote Binder handle to a local Layer::Handle and reads its owner field from unrelated object memory. Exploitation requires user interaction but no additional execution privileges and can execute code with elevated privileges.
