      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\niommu/vt-d: Fix WARN_ON in iommu probe path\n\nCommit 1a75cc710b95 (\"iommu/vt-d: Use rbtree to track iommu probed\ndevices\") adds all devices probed by the iommu driver in a rbtree\nindexed by the source ID of each device. It assumes that each device\nhas a unique source ID. This assumption is incorrect and the VT-d\nspec doesn't state this requirement either.\n\nThe reason for using a rbtree to track devices is to look up the device\nwith PCI bus and devfunc in the paths of handling ATS invalidation time\nout error and the PRI I/O page faults. Both are PCI ATS feature related.\n\nOnly track the devices that have PCI ATS capabilities in the rbtree to\navoid unnecessary WARN_ON in the iommu probe path. Otherwise, on some\nplatforms below kernel splat will be displayed and the iommu probe results\nin failure.\n\n WARNING: CPU: 3 PID: 166 at drivers/iommu/intel/iommu.c:158 intel_iommu_probe_device+0x319/0xd90\n Call Trace:\n  <TASK>\n  ? __warn+0x7e/0x180\n  ? intel_iommu_probe_device+0x319/0xd90\n  ? report_bug+0x1f8/0x200\n  ? handle_bug+0x3c/0x70\n  ? exc_invalid_op+0x18/0x70\n  ? asm_exc_invalid_op+0x1a/0x20\n  ? intel_iommu_probe_device+0x319/0xd90\n  ? debug_mutex_init+0x37/0x50\n  __iommu_probe_device+0xf2/0x4f0\n  iommu_probe_device+0x22/0x70\n  iommu_bus_notifier+0x1e/0x40\n  notifier_call_chain+0x46/0x150\n  blocking_notifier_call_chain+0x42/0x60\n  bus_notify+0x2f/0x50\n  device_add+0x5ed/0x7e0\n  platform_device_add+0xf5/0x240\n  mfd_add_devices+0x3f9/0x500\n  ? preempt_count_add+0x4c/0xa0\n  ? up_write+0xa2/0x1b0\n  ? __debugfs_create_file+0xe3/0x150\n  intel_lpss_probe+0x49f/0x5b0\n  ? pci_conf1_write+0xa3/0xf0\n  intel_lpss_pci_probe+0xcf/0x110 [intel_lpss_pci]\n  pci_device_probe+0x95/0x120\n  really_probe+0xd9/0x370\n  ? __pfx___driver_attach+0x10/0x10\n  __driver_probe_device+0x73/0x150\n  driver_probe_device+0x19/0xa0\n  __driver_attach+0xb6/0x180\n  ? __pfx___driver_attach+0x10/0x10\n  bus_for_each_dev+0x77/0xd0\n  bus_add_driver+0x114/0x210\n  driver_register+0x5b/0x110\n  ? __pfx_intel_lpss_pci_driver_init+0x10/0x10 [intel_lpss_pci]\n  do_one_initcall+0x57/0x2b0\n  ? kmalloc_trace+0x21e/0x280\n  ? do_init_module+0x1e/0x210\n  do_init_module+0x5f/0x210\n  load_module+0x1d37/0x1fc0\n  ? init_module_from_file+0x86/0xd0\n  init_module_from_file+0x86/0xd0\n  idempotent_init_module+0x17c/0x230\n  __x64_sys_finit_module+0x56/0xb0\n  do_syscall_64+0x6e/0x140\n  entry_SYSCALL_64_after_hwframe+0x71/0x79",
