Summary
[Regression] Uninstalling of packages by DPC does not work in T
Details

In getStringsForPrefix of Settings.java, there is a possible prevention of package uninstallation due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
