In the Linux kernel, the following vulnerability has been resolved:
Input: ims-pcu - validate control endpoint type
The driver currently assumes that the first endpoint of the control interface is an interrupt IN endpoint without verifying it. A malicious device could provide a different endpoint type, which would then be passed to usb_fill_int_urb(), potentially leading to kernel warnings or undefined behavior.
Verify that the control endpoint is an interrupt IN endpoint.
