Subject: [PATCH] [BACKPORT] Disallow unexpected incoming HID connections 2/2
|
|
|
|
HID profile accepted any new incoming HID connection. Even when the
|
|
connection policy disabled HID connection, remote devices could initiate
|
|
HID connection.
|
|
This change ensures that incoming HID connection are accepted only if
|
|
application was interested in that HID connection.
|
|
This vulnerarbility no longer exists on the main because of feature
|
|
request b/324093729.
|
|
|
|
Test: Manual | Pair and connect a HID device, disable HID connection
|
|
from Bluetooth device setting, attempt to connect from the HID device.
|
|
