CVE-2020-0045

Local privilege escalation via unsynchronized ShellSubscriber initialization

Published Mar 10, 2020 · Updated Aug 4, 2024

Local privilege escalation in Android 10's StatsService allows local users with System privileges to gain elevated execution privileges. StatsService::command lazily initializes a shared ShellSubscriber pointer without thread-safe synchronization, allowing concurrent calls to corrupt memory. A null ResultReceiver can repeatedly crash statsd until the race is won; exploitation requires System-level execution and no user interaction.
