CVE-2024-25741

A flaw was found in the f_printer driver in the Linux kernel. Due to an incorrect use of the USB Gadget API, the printer_write function in the drivers/usb/gadget/function/f_printer.c file can trigger a WARN_ON_ONCE in the usb_ep_queue function in the drivers/usb/gadget/udc/core.c file, resulting in a denial of service.

The kernel as shipped by Red Hat Enterprise Linux 8 is not affected by this vulnerability because the f_printer and the USB Gadget driver/API is not enabled. In Red Hat Enterprise Linux 9, the f_printer driver is not enable as well, but the USB Gadget driver/API, where the WARN_ON_ONCE is triggered, is available in the aarch64 architecture.
