success does not depend on races or other conditions outside attacker control.\nPR:L - Exploitation requires access to the VFIO device/migration FD (typically a qemu/kvm-group process with an assigned ACC VF), which is low privilege relative to full root and does not require init-namespace CAP_SYS_ADMIN once the device is assigned.\nUI:N - No separate victim action is required; the attacker (or their VMM process) initiates migration state transitions and I/O on the migration FD themselves.\nS:U - The flaw is in the host VFIO migration driver and impacts the same host security authority (device/IOMMU faults and PF error reporting); it is not a guest-to-host escape or IOMMU bypass.\nC:N - Both the buggy read and write stay within the bounded acc_vf_data object and only mishandle the intended migration payload; there is no out-of-bounds or unauthorized kernel memory disclosure.\nI:H - Corrupted migration contents are loaded into hardware via vf_qm_load_data (registers and DMA addresses such as eqe/aeqe/sqc/cqc), so device configuration integrity is fully compromised and shared PF state can be affected.\nA:H - Loading the corrupted state causes SMMU translation faults, QM AXI response errors, and doorbell timeouts that render the accelerator VF (and potentially PF services) unavailable." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/vfio/pci/hisilicon/hisi_acc_vfio_pci.c" ], "versions": [ { "version": "d9a871e4a143047d1d84a606772af319f11516f9", "lessThan": "45f80b2f230df10600e6fa1b83b28bf1c334185e", "status": "affected", "versionType": "git" }, { "version": "d9a871e4a143047d1d84a606772af319f11516f9", "lessThan": "6bda81e24a35a856f58e6a5786de579b07371603", "status": "affected", "versionType": "git" }, { "version": "d9a871e4a143047d1d84a606772af319f11516f9", "lessThan": "be12ad45e15b5ee0e2526a50266ba1d295d26a88", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/vfio/pci/hisilicon/hisi_acc_vfio_pci.c" ], "versions": [ { "version": "6.2", "status": "affected" }, { "version": "0", "lessThan": "6.2", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.14", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.7.2", "lessThanOrEqual": "6.7.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.8", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ] } ], "cpeApplicability": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.2", "versionEndExcluding": "6.6.14" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.2", "versionEndExcluding": "6.7.2" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.2", "versionEndExcluding": "6.8" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/45f80b2f230df10600e6fa1b83b28bf1c334185e" }, { "url": "https://git.kernel.org/stable/c/6bda81e24a35a856f58e6a5786de579b07371603" }, { "url": "https://git.kernel.org/stable/c/be12ad45e15b5ee0e2526a50266ba1d295d26a88" } ], "title": "hisi_acc_vfio_pci: Update migration data pointer correctly on saving/resume", "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": 5.5, "attackVector": "LOCAL", "baseSeverity": "MEDIUM", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H", "integrityImpact": "NONE", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "HIGH", "privilegesRequired": "LOW", "confidentialityImpact": "NONE" } }, { "other": { "type": "ssvc", "content": { "timestamp": "2025-10-01T19:12:05.859768Z", "id": "CVE-2023-52453", "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": "2025-10-01T19:12:14.044Z" } }, { "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T23:03:19.607Z" }, "title": "CVE Program Container", "references": [ { "url": "https://git.kernel.org/stable/c/45f80b2f230df10600e6fa1b83b28bf1c334185e", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/6bda81e24a35a856f58e6a5786de579b07371603", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/be12ad45e15b5ee0e2526a50266ba1d295d26a88", "tags": [ "x_transferred" ] } ] } ] } }
