CVE-2026-90034

CVE-2026-90034 affects the Linux kernel's usb_mdc800 driver (USB Image MDC800). The root cause is the use of kmalloc() instead of kzalloc() for the irq_urb_buffer and download_urb_buffer allocations in usb_mdc800_init(). Because the memory is not zero-initialized, a shorter-than-expected message ...
