CVE-2026-45923: Linux

Описание

Оригинално описание

In the Linux kernel, the following vulnerability has been resolved: net: usb: catc: enable basic endpoint checking catc_probe() fills three URBs with hardcoded endpoint pipes without verifying the endpoint descriptors: - usb_sndbulkpipe(usbdev, 1) and usb_rcvbulkpipe(usbdev, 1) for TX/RX - usb_rcvintpipe(usbdev, 2) for interrupt status A malformed USB device can present these endpoints with transfer types that differ from what the driver assumes. Add a catc_usb_ep enum for endpoint numbers, replacing magic constants throughout. Add usb_check_bulk_endpoints() and usb_check_int_endpoints() calls after usb_set_interface() to verify endpoint types before use, rejecting devices with mismatched descriptors at probe time. Similar to - commit 90b7f2961798 ("net: usb: rtl8150: enable basic endpoint checking") which fixed the issue in rtl8150.
