CVE-2021-25418

Local arbitrary activity execution via unprotected component

Published Jun 11, 2021 · Updated Aug 3, 2024

Improper component protection in Samsung Internet before 14.0.1.62 allows untrusted applications to execute arbitrary activities. The affected component and missing protection check are not publicly disclosed by Samsung, so the exact activity-launch mechanism remains unspecified. Exploitation requires a malicious application on the same device; the documented impact is execution of an arbitrary activity under the vulnerable condition.
