The subsystem allows multiple\nuser space listeners to the region, while data of the payload was likely\nreleased before the listeners execute read(2) to access to it for copying\nto user space.\n\nThe issue was fixed by a commit 281e20323ab7 (\"firewire: core: fix\nuse-after-free regression in FCP handler\"). The object of payload is\nduplicated in kernel space for each listener.

Este parche es una correcci\u00f3n para el kernel de Linux v2.6.33 o posterior. Para la subacci\u00f3n de solicitud a la regi\u00f3n FCP IEC 61883-1, el subsistema FireWire de Linux ha tenido un problema de use-after-free. El subsistema permite que varios oyentes del espacio de usuario accedan a la regi\u00f3n, mientras que los datos de el payload probablemente se liberaron antes de que los oyentes ejecutaran read(2) para acceder a ellos para copiarlos al espacio de usuario. El problema se solucion\u00f3 mediante un commit 281e20323ab7 (\"firewire: core: correcci\u00f3n de la regresi\u00f3n de use-after-free en el controlador FCP\"). El objeto de el payload se duplica en el espacio del kernel para cada oyente. Cuando el oyente ejecuta ioctl(2) con la solicitud FW_CDEV_IOC_SEND_RESPONSE, el objeto se liberar\u00e1.
