Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
HID: quirks: Add quirk for 2 Chicony Electronics HP 5MP Cameras<br />
<br />
The Chicony Electronics HP 5MP Cameras (USB ID 04F2:B824 & 04F2:B82C)<br />
report a HID sensor interface that is not actually implemented.<br />
Attempting to access this non-functional sensor via iio_info causes<br />
system hangs as runtime PM tries to wake up an unresponsive sensor.<br />
<br />
Add these 2 devices to the HID ignore list since the sensor interface is<br />
non-functional by design and should not be exposed to userspace.
