CVE-2023-52559

影响性分析说明：
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:

CVE-2023-52559

影响性分析说明：
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().
