CVE-2025-21077

Privileged activity launch via undisclosed input flaw

Published Nov 5, 2025 · Updated Nov 5, 2025

Improper input validation in Samsung Email before 6.2.06.0 allows local users to launch arbitrary activities with the app's privileges. Samsung has not disclosed the vulnerable component, rejected input, or operation reached by that input; the advisory identifies only unused code. A local low-privileged app is sufficient and no user interaction is required; Samsung's assessment limits impact to low confidentiality loss.
