"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nInput: synaptics - fix crash when enabling pass-through port\n\nWhen enabling a pass-through port an interrupt might come before psmouse\ndriver binds to the pass-through port. However synaptics sub-driver\ntries to access psmouse instance presumably associated with the\npass-through port to figure out if only 1 byte of response or entire\nprotocol packet needs to be forwarded to the pass-through port and may\ncrash if psmouse instance has not been attached to the port yet.\n\nFix the crash by introducing open() and close() methods for the port and\ncheck if the port is open before trying to access psmouse instance.\nBecause psmouse calls serio_open() only after attaching psmouse instance\nto serio port instance this prevents the potential crash."

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: Entrada: synaptics - arregla el fallo al habilitar el puerto de paso Al habilitar un puerto de paso, puede aparecer una interrupci\u00f3n antes de que el controlador psmouse se vincule al puerto de paso. Sin embargo, el subcontrolador synaptics intenta acceder a la instancia psmouse presuntamente asociada con el puerto de paso para averiguar si solo se necesita reenviar 1 byte de respuesta o el paquete de protocolo completo al puerto de paso y puede bloquearse si la instancia psmouse a\u00fan no se ha adjuntado al puerto. Arregla el bloqueo introduciendo los m\u00e9todos open() y close() para el puerto y comprueba si el puerto est\u00e1 abierto antes de intentar acceder a la instancia psmouse. Debido a que psmouse llama a serio_open() solo despu\u00e9s de adjuntar la instancia psmouse a la instancia del puerto serio, esto evita el posible bloqueo."
