CVE-2024-25741Public exploit

System crash via disabled USB endpoint queue

Published Feb 12, 2024 · Updated Nov 3, 2025

Improper endpoint-state validation in the Linux kernel through 6.7.4 allows local users to crash the system through a gadget-printer write. The printer_write function queues a USB request through usb_ep_queue without first rejecting writes made while the IN endpoint is disabled. A low-privileged process must access the configured USB Gadget printer device and issue a write before endpoint enablement, triggering a kernel warning and service interruption.
