CVE-2022-20543

Display crash loop via unbounded animation scales

Published Dec 16, 2022 · Updated Apr 21, 2025

Denial of service in Android 13 Framework allows local users with system privileges to trigger a persistent display crash loop. WindowManager accepts unbounded transition, animator, and window animation-scale settings instead of constraining each value to 0 through 20. System execution privileges are required, and exploitation interrupts display availability without user interaction.
