CVE-2021-25359

Local AP information disclosure via improper SELinux policy

Published Apr 9, 2021 · Updated Aug 3, 2024

Improper access control in Samsung Mobile Devices on Android 10 and 11 allows local attackers to read AP information via untrusted applications. An overly permissive SELinux policy grants an untrusted application access to AP information that the platform should restrict. Execution of an attacker-controlled application on an affected device is required, and the reported consequence is limited to AP-information disclosure.
