CVE-2026-64346

Summary: CVE-2026-64346 affects the Linux kernel USB gadget udc path. A race condition can occur when the udc (managing gadget state) is freed by usb_del_gadget() while gadget_match_driver() may still access the freed udc (e.g., via configfs). This Use-After-Free can trigger a NULL pointer derefe...
