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 the updateSettingsInternalLI function of InstallPackageHelper.java, allowing an app to be sideloaded in the work profile. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not required for exploitation.

Recommendations For versions prior to the fixed version, consider restricting access to the updateSettingsInternalLI function of InstallPackageHelper.java to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
