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.
|
|
|

Bug: 258653813
