CVE-2023-20916

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

Description A possible way to bypass restrictions on starting activities from the background exists due to a missing permission check in the getMainActivityLaunchIntent function of LauncherAppsService.java. 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 Android-12 through Android-12L, consider restricting the use of the getMainActivityLaunchIntent function in LauncherAppsService.java until a patch is available. As a temporary workaround, review and enforce permission checks for starting activities from the background to minimize the risk of exploitation.
