"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: roles: fix NULL pointer issue when put module's reference\n\nIn current design, usb role class driver will get usb_role_switch parent's\nmodule reference after the user get usb_role_switch device and put the\nreference after the user put the usb_role_switch device. However, the\nparent device of usb_role_switch may be removed before the user put the\nusb_role_switch. If so, then, NULL pointer issue will be met when the user\nput the parent module's reference.\n\nThis will save the module pointer in structure of usb_role_switch. Then,\nwe don't need to find module by iterating long relations."

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: usb: roles: soluciona el problema del puntero NULL al colocar la referencia del m\u00f3dulo. En el dise\u00f1o actual, el controlador de clase de rol usb obtendr\u00e1 la referencia del m\u00f3dulo principal usb_role_switch despu\u00e9s de que el usuario obtenga el dispositivo usb_role_switch y coloque la referencia despu\u00e9s del El usuario puso el dispositivo usb_role_switch. Sin embargo, el dispositivo principal de usb_role_switch se puede eliminar antes de que el usuario coloque usb_role_switch. Si es as\u00ed, entonces, el problema del puntero NULL se solucionar\u00e1 cuando el usuario coloque la referencia del m\u00f3dulo principal. Esto guardar\u00e1 el puntero del m\u00f3dulo en la estructura de usb_role_switch. Entonces, no necesitamos encontrar el m\u00f3dulo iterando relaciones largas."
