Subject: [PATCH] Fix security vulnerability of non-dynamic permission removal
|
|
|
|
The original removePermission() code in PermissionManagerService
|
|
missed a logical negation operator when handling non-dynamic
|
|
permissions, causing both
|
|
testPermissionPermission_nonDynamicPermission_permissionUnchanged and
|
|
testRemovePermission_dynamicPermission_permissionRemoved tests in
|
|
DynamicPermissionsTest to fail.
|
|
|
|
The corresponding test DynamicPermissionsTest is also updated in the
|
|
other CL: ag/27073864
|
|
|
|
Bug: 321711213
|
|
Test: DynamicPermissionsTest on sc-dev and tm-dev locally
|
|
