      "title": "iommu/vt-d: Tear down scalable-mode context on probe failure",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\niommu/vt-d: Tear down scalable-mode context on probe failure\n\nintel_pasid_setup_sm_context() walks a PCI device’s DMA aliases via\npci_for_each_dma_alias() and programs a scalable-mode context entry for\neach RID. For a device with a dma_alias_mask, the callback is invoked\nonce for the device’s own RID and once for each alias bit, all with the\nsame pci_dev, so device_pasid_table_setup() runs for multiple RIDs.\n\npci_for_each_dma_alias() stops at the first callback error. Therefore, a\nfailure partway through the walk can leave context entries for already\nprocessed RIDs present and still pointing to the device’s PASID table.\n\nOn this error path, intel_iommu_probe_device() currently jumps directly\nto intel_pasid_free_table(), which frees the PASID table without\nfirst tearing down those context entries. The IOMMU may then walk a\npresent context entry whose PASID table pointer references freed\nmemory.\n\nintel_iommu_release_device() already performs teardown before freeing the\ntable. Apply the same ordering on the probe failure path.\n\ndevice_pasid_table_teardown() safely handles RIDs that were never\nprogrammed: iommu_context_addr() returns NULL when no context table has\nbeen allocated, and clearing the Present bit of an already non-present\nentry is a no-op. So unwind is safe for both the alias that failed and\nany aliases not yet reached.",
