There is no listing in CISA's KEV catalog, meaning no known active exploit out there.

The impact is local escalation, allowing the attacker to read private data from other apps."}}}}, "created": "2026-03-03T08:41:12.136023+00:00", "title": "ActivityManagerService Local Escalation via Missing Permission Check", "updated": "2026-04-16T14:30:16.127952+00:00", "vendors": ["google", "google$PRODUCT$android"]}
