Vulnerability from cvelistv5
Published

Modified

Severity ?
9.3 (Critical) - CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Force requesting ACS when tboot is enabled Currently the conditions of requesting ACS in detect_intel_iommu() don't include tboot, leading to a possible misconfiguration with ACS disabled (e.g. due to user opts) while iommu is later forced on by tboot_force_iommu(). Fix it by checking tboot in detect_intel_iommu().

This is not a network-protocol path.\\nAC:L - On a tboot launch where intel_iommu=off, iommu=off, or default dmar_disabled skipped pci_request_acs(), ACS SV/RR/CR/UF/TB are never programmed; an attacker-controlled device can then deterministically perform P2P DMA or RID spoofing with no race or layout luck.\\nPR:N - A malicious PCIe/Thunderbolt device or a tenant with an assigned passthrough/SR-IOV function issues the DMA itself and needs no host account, capability, or init-namespace root, matching other VT-d isolation-bypass scores for unauthenticated devices.\\nUI:N - After the kernel boots with tboot-forced VT-d and ACS still disabled, the attacker\\u2019s device performs DMA on its own; no separate victim action such as mounting a filesystem or opening a file is required.\\nS:C - Missing ACS lets a device spoof requester IDs and send peer-to-peer TLPs that never reach the IOMMU, crossing the device/host DMA isolation boundary that tboot forces VT-d on to enforce (IOMMU/DMA boundary bypass is Scope Changed).\\nC:H - Without ACS source validation, request redirect, and translation blocking, a device can impersonate another requester ID or DMA to peer BARs, reading host or peer-device memory outside its IOMMU domain (arbitrary DMA disclosure).\\nI:H - The same ACS gap yields DMA writes into host or peer-device memory, including ATS without translation blocking on external/untrusted ports, providing an arbitrary write primitive that can corrupt kernel memory and hijack control flow.\\nA:H - Unchecked DMA writes and IOMMU-bypassing P2P traffic can corrupt kernel structures or provoke DMAR faults, oopses, and panics; any such host crash qualifies as High availability impact.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"5d990b627537e59a3a2f039ff588a4750e9c1a6a\", \"lessThan\": \"579eb867d3da63f3b5e32f235925e1daa7ec70d0\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"5d990b627537e59a3a2f039ff588a4750e9c1a6a\", \"lessThan\": \"aaeb81241e802c86be69394f72d49fde3f861fbb\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"5d990b627537e59a3a2f039ff588a4750e9c1a6a\", \"lessThan\": \"45705a6bfdb283f7b3b509010fd617b72f942537\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"5d990b627537e59a3a2f039ff588a4750e9c1a6a\", \"lessThan\": \"87bc611c6c98a41c00feb7b06b0c297dd141a2ae\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"5d990b627537e59a3a2f039ff588a4750e9c1a6a\", \"lessThan\": \"607432b2618b61df81134be0ef2562b8300c1216\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/iommu/intel/dmar.c\", \"drivers/iommu/intel/iommu.c\", \"drivers/iommu/intel/iommu.h\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"2.6.33\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"2.6.33\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"6.6.157\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.109\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.18.50\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.18.*\"}, {\"status\": \"unaffected\", \"version\": \"7.2.4\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"7.2.*\"}, {\"status\": \"unaffected\", \"version\": \"7.3\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/iommu/intel/dmar.c\", \"drivers/iommu/intel/iommu.c\", \"drivers/iommu/intel/iommu.h\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/579eb867d3da63f3b5e32f235925e1daa7ec70d0\"}, {\"url\": \"https://git.kernel.org/stable/c/aaeb81241e802c86be69394f72d49fde3f861fbb\"}, {\"url\": \"https://git.kernel.org/stable/c/45705a6bfdb283f7b3b509010fd617b72f942537\"}, {\"url\": \"https://git.kernel.org/stable/c/87bc611c6c98a41c00feb7b06b0c297dd141a2ae\"}, {\"url\": \"https://git.kernel.org/stable/c/607432b2618b61df81134be0ef2562b8300c1216\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\niommu/vt-d: Force requesting ACS when tboot is enabled\\n\\nCurrently the conditions of requesting ACS in detect_intel_iommu()\\ndon\u0027t include tboot, leading to a possible misconfiguration with ACS\\ndisabled (e.g. due to user opts) while iommu is later forced on by\\ntboot_force_iommu().\\n\\nFix it by checking tboot in detect_intel_iommu().\"}], \"cpeApplicability\": [{\"nodes\": [{\"negate\": false, \"cpeMatch\": [{\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.6.157\", \"versionStartIncluding\": \"2.6.33\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.12.109\", \"versionStartIncluding\": \"2.6.33\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.18.50\", \"versionStartIncluding\": \"2.6.33\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"7.2.4\", \"versionStartIncluding\": \"2.6.33\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"7.3\", \"versionStartIncluding\": \"2.6.33\"}], \"operator\": \"OR\"}]}], \"providerMetadata\": {\"orgId\": \"416baaa9-dc9f-4396-8d5f-8c081fb06d67\", \"shortName\": \"Linux\", \"dateUpdated\": \"2026-10-19T08:46:57.768Z\"}}}",
