In the Linux kernel, the following vulnerability has been resolved:
net: usb: pegasus: enable basic endpoint checking
pegasus_probe() fills URBs with hardcoded endpoint pipes without verifying the endpoint descriptors:
A malformed USB device can present these endpoints with transfer types that differ from what the driver assumes.
Add a pegasus_usb_ep enum for endpoint numbers, replacing magic constants throughout. Add usb_check_bulk_endpoints() and usb_check_int_endpoints() calls before any resource allocation to verify endpoint types before use, rejecting devices with mismatched descriptors at probe time, and avoid triggering assertion.
