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

Description The issue is related to a missing permission check in the onCreate method of ManagePermissionsActivity.java. This could allow bypassing factory reset protections, leading to local escalation of privilege with physical access to a device that has been factory reset, and no additional execution privileges are needed. User interaction is not required for exploitation.

Recommendations For Android versions prior to the fixed version, consider restricting access to the ManagePermissionsActivity.java until a patch is available. As a temporary workaround, disabling the onCreate method of ManagePermissionsActivity.java may help minimize the risk of exploitation. However, this should be done with caution and only by experienced users, as it may have unintended consequences on device functionality. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
