CVE-2020-0126Public exploit

System code execution via DRM object lifetime race

Published Jun 11, 2020 · Updated Aug 4, 2024

Use-after-free in DrmPlugin.cpp in Google Android 10 allows local users to execute code with System privileges through a race condition. ClearKey DRM secure-stop methods access a shared map without locking while another thread can clear it, leaving freed entries in use. Exploitation requires System execution privileges but no user interaction, and successful abuse executes code in that privileged context.
