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

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."
