From 18e77f27aa09c39aa0265ec19f302e6bf3280cfc Mon Sep 17 00:00:00 2001 From: Yanting Yang Date: Wed, 4 Jan 2023 09:40:38 +0000 Subject: [PATCH] Add DISALLOW_APPS_CONTROL check into uninstall app for all users Settings App info page supports a "Uninstall for all users" function when multiple users are enabled. It bypasses the restriction of DISALLOW_APPS_CONTROL which breaks the user isolation guideline. To fix this vulnerability, we should check the DISALLOW_APPS_CONTROL restriction to provide the "Uninstall for all users" function.
