Description

In the SELinux policy configured in system_app.te, there is a possible way for system_app to gain code execution in other processes due to an overly-permissive SELinux policy. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-11Android ID: A-188554048
