Local privilege escalation via unsanitized app labels
Published Jun 1, 2026 · Updated Jun 1, 2026
UI spoofing in CertInstaller in Google Android 14, 15, 16, and 16 QPR2 allows local users to gain elevated privileges. The getCallingAppLabel method renders an application-controlled label with loadLabel, allowing newline characters to push the CA certificate warning off-screen. The gate is execution of a locally installed malicious application with ordinary privileges; no additional user interaction is required for privilege escalation.
