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

Description In app uninstallation, there is a possible set of permissions that may not be removed from a shared app ID. This could lead to a local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation.

Recommendations For Android version Android-10, consider restricting the use of shared app IDs to minimize the risk of exploitation until a patch is available. As a temporary workaround, ensure that all permissions are manually reviewed and removed when uninstalling apps to prevent potential privilege escalation.
