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.
