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 \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" ] } ] } ] } }
