CVE-2021-39662

Name of the Vulnerable Software and Affected Versions Android versions Android-11 through Android-12

Description A missing permission check in the checkUriPermission function of MediaProvider.java allows access to the content of media provider collections. This could lead to local escalation of privilege, requiring User execution privileges. No user interaction is needed for exploitation.

Recommendations For Android versions Android-11 through Android-12, consider restricting access to the MediaProvider until a patch is available. As a temporary workaround, consider disabling the checkUriPermission function in MediaProvider.java to minimize the risk of exploitation.
