CVE-2024-34720

Local privilege escalation via unchecked Zygote peer UID

Published Jul 9, 2024 · Updated Aug 2, 2024

Privilege escalation in Google Android 12 through 14 allows local users to execute arbitrary code in another app zygote process. The native Zygote command loop forwards a non-fork command to the Java layer without validating the new connection's peer UID. Exploitation requires local code execution and knowledge of another app zygote's random socket address; no user interaction is required.
