Local privilege escalation via misidentified activity caller
Published Sep 11, 2024 · Updated Oct 16, 2024
Permission bypass in Google Android 12, 12L, 13, and 14 allows local users to elevate privileges through a Settings search result launch. SearchResultTrampoline uses getCallingActivity() to authorize the result recipient rather than the package that launched the activity or built its PendingIntent. Exploitation requires user interaction and lets a local app pass the launcher allowlist check, producing local privilege escalation.
