In the Linux kernel, the following vulnerability has been resolved:

iommu/vt-d: Avoid memory allocation in iommu_suspend()

The iommu_suspend() syscore suspend callback is invoked with IRQ disabled. Allocating memory with the GFP_KERNEL flag may re-enable IRQs during the suspend callback, which can cause intermittent suspend/hibernation problems with the following kernel traces:

Given that only 4 words memory is needed, avoid the memory allocation in iommu_suspend().
