"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nvfio/fsl-mc: Block calling interrupt handler without trigger\n\nThe eventfd_ctx trigger pointer of the vfio_fsl_mc_irq object is\ninitially NULL and may become NULL if the user sets the trigger\neventfd to -1. The interrupt handler itself is guaranteed that\ntrigger is always valid between request_irq() and free_irq(), but\nthe loopback testing mechanisms to invoke the handler function\nneed to test the trigger. The triggering and setting ioctl paths\nboth make use of igate and are therefore mutually exclusive.\n\nThe vfio-fsl-mc driver does not make use of irqfds, nor does it\nsupport any sort of masking operations, therefore unlike vfio-pci\nand vfio-platform, the flow can remain essentially unchanged."

"value": "En el kernel de Linux, se resolvi\u00f3 la siguiente vulnerabilidad: vfio/fsl-mc: Bloquear el controlador de interrupciones de llamada sin disparador. El puntero de disparo eventfd_ctx del objeto vfio_fsl_mc_irq es inicialmente NULL y puede convertirse en NULL si el usuario establece el disparador eventfd en -1. El propio controlador de interrupciones garantiza que el disparador siempre ser\u00e1 v\u00e1lido entre request_irq() y free_irq(), pero los mecanismos de prueba de bucle invertido para invocar la funci\u00f3n del controlador deben probar el disparador. Las rutas de activaci\u00f3n y configuraci\u00f3n de ioctl utilizan igate y, por lo tanto, son mutuamente excluyentes. El controlador vfio-fsl-mc no utiliza irqfds ni admite ning\u00fan tipo de operaci\u00f3n de enmascaramiento; por lo tanto, a diferencia de vfio-pci y vfio-platform, el flujo puede permanecer esencialmente sin cambios."
