In the Linux kernel, the following vulnerability has been resolved: usb: image: mdc800: change kmalloc() to kzalloc() Change the kmalloc() calls in usb_mdc800_init() for irq_urb_buffer and download_urb_buffer to kzalloc(), avoiding potential stack leaks if a shorter message is received in mdc800_usb_irq() and mdc800_usb_download_notify()
