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"}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/iommu/intel/iommu.c"],"versions":[{"version":"c618d446f1d64bdc9e426bab5e8619f224cde2ae","lessThan":"fba8ca3e6f608b92e54271fdbd3ce569361939fc","status":"affected","versionType":"git"},{"version":"1a75cc710b956010137b4fe1d1fa3282bfd8f86c","lessThan":"89436f4f54125b1297aec1f466efd8acb4ec613d","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/iommu/intel/iommu.c"],"versions":[{"version":"6.8.2","lessThan":"6.8.7","status":"affected","versionType":"semver"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.8.2","versionEndExcluding":"6.8.7"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/fba8ca3e6f608b92e54271fdbd3ce569361939fc"},{"url":"https://git.kernel.org/stable/c/89436f4f54125b1297aec1f466efd8acb4ec613d"}],"title":"iommu/vt-d: Fix WARN_ON in iommu probe path","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"problemTypes":[{"descriptions":[{"type":"CWE","lang":"en","description":"CWE-noinfo Not enough information"}]}],"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":5.9,"attackVector":"LOCAL","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","integrityImpact":"LOW","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"LOW","privilegesRequired":"NONE","confidentialityImpact":"LOW"}},{"other":{"type":"ssvc","content":{"timestamp":"2024-05-20T14:23:39.677207Z","id":"CVE-2024-35957","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-11-05T21:46:31.238Z"}},{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T03:21:49.034Z"},"title":"CVE Program Container","references":[{"url":"https://git.kernel.org/stable/c/fba8ca3e6f608b92e54271fdbd3ce569361939fc","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/89436f4f54125b1297aec1f466efd8acb4ec613d","tags":["x_transferred"]}]}]}}
