Description

In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Tear down scalable-mode context on probe failure intel_pasid_setup_sm_context() walks a PCI device’s DMA aliases via pci_for_each_dma_alias() and programs a scalable-mode context entry for each RID. For a device with a dma_alias_mask, the callback is invoked once for the device’s own RID and once for each alias bit, all with the same pci_dev, so device_pasid_table_setup() runs for multiple RIDs. pci_for_each_dma_a
