Upstream information
Description
In the Linux kernel, the following vulnerability has been resolved:ALSA: usb-audio: avoid kobject path lookup in DualSense match
The DualSense jack-detection input handler verifies that a matching input
device belongs to the same physical controller by building kobject path
strings for both the input device and the USB audio device, then comparing
the path prefix.
This was observed when a weak physical connection caused the controller
to rapidly disconnect and reconnect. During that repeated hotplug,
snd_dualsense_ih_match() can run while the controller's USB device is
being disconnected. kobject_get_path() walks ancestor kobjects and
dereferences their names; if the USB device kobject name is no longer
valid, this can fault in strlen():
RIP: 0010:strlen+0x10/0x30
Call Trace:
kobject_get_path+0x34/0x150
snd_dualsense_ih_match+0x49/0xd0 [snd_usb_audio]
input_register_device+0x566/0x6a0
ps_probe+0xb89/0x1590 [hid_playstation]
The same ownership check can be done without building kobject path
strings. The input device is parented below the HID device, USB interface
and USB device, so walking the input device parent chain and comparing
against the mixer USB device preserves the check without dereferencing
kobject names during disconnect.
