High CVSS 8.8
Summary
In the Linux kernel, the following vulnerability has been resolved: powerpc/pseries/iommu: IOMMU incorrectly marks MMIO range in DDW Power Hypervisor can possibily allocate MMIO window intersecting with Dynamic DMA Window (DDW) range, which is over 32-bit addressing. These MMIO pages needs to be marked as reserved so that IOMMU doesn't map DMA buffers in this range. The current code is not marking these pages correctly which is resulting in LPAR to OOPS while booting. The stack is at below …
