CVE-2021-39750

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 PackageManager, allowing the splash screen theme of other apps to be changed. 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 PackageManager until a patch is available. As a temporary workaround, avoid using the affected PackageManager functionality to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
