AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions: Android versions Android-10 through Android-11

Description: The issue is related to a permissions bypass in the onPackageAddedInternal method of PermissionManagerService.java, which could allow access to external storage. This might lead to a local escalation of privilege, requiring User execution privileges. No user interaction is needed for exploitation.

Recommendations: For Android versions Android-10 through Android-11, consider restricting access to external storage until a patch is available. As a temporary workaround, review and restrict permissions related to the PermissionManagerService to minimize the risk of exploitation.
