CVE-2026-43156 Detail

Description

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: - usb_rcvbulkpipe(dev, 1) for RX data - usb_sndbulkpipe(dev, 2) for TX data - usb_rcvintpipe(dev, 3) for status interrupts 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. Similar fix to - commit 90b7f2961798 ("net: usb: rtl8150: enable basic endpoint checking") - commit 9e7021d2aeae ("net: usb: catc: enable basic endpoint checking")
