Name of the Vulnerable Software and Affected Versions Android versions prior to the fixed version

Description A permissions bypass issue in multiple functions of WifiCallingSettings.java allows changing calling preferences for the admin user. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not required for exploitation.

Recommendations For Android versions prior to the fixed version, consider restricting access to the WifiCallingSettings.java functions until a patch is available. As a temporary workaround, limit the ability to change calling preferences for the admin user to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
