Per kernel scoring guidance, netlink-reachable code is Local.\nAC:L - The out-of-bounds read is fully deterministic — every MGMTDEV_GET doit or dump against a vp_vdpa management device walks past the single-entry allocation with no race, timing window, or attacker-uninfluenceable memory layout required.\nPR:L - VDPA_CMD_MGMTDEV_GET is registered without GENL_ADMIN_PERM (drivers/vdpa/vdpa.c:1544), unlike the sibling DEV_NEW/DEV_DEL/DEV_ATTR_SET ops, so any unprivileged local user can trigger the read and receive the reply; the dump variant needs no attributes at all.\nUI:N - The attacker triggers the bug entirely on their own by sending a netlink message; no victim action or cooperation is involved.\nS:U - The out-of-bounds read stays within the kernel's own heap and the impact is confined to the kernel security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The read is unbounded — it walks adjacent slab memory until it chances upon a zero word — and the derived value is returned to the unprivileged caller in VDPA_ATTR_DEV_MGMTDEV_SUPPORTED_CLASSES, disclosing adjacent heap contents rather than a strictly bounded few bytes.\nI:L - Garbage device IDs harvested out of bounds are folded into the classes bitmask and ncls counter that gate the class-consistency validation in vdpa_nl_cmd_dev_add_set_doit(), so out-of-bounds heap data can alter kernel device-creation decisions in a limited way.\nA:H - The unterminated walk can run far past the object into a non-present region and oops the kernel, and on KASAN-instrumented builds the slab-out-of-bounds report panics under panic_on_warn; the read is repeatable at will by an unprivileged user." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/vdpa/virtio_pci/vp_vdpa.c" ], "versions": [ { "version": "ffbda8e9df10d1784d5427ec199e7d8308e3763f", "lessThan": "870d68fe17b5d9032049dcad98b5781a344a8657", "status": "affected", "versionType": "git" }, { "version": "ffbda8e9df10d1784d5427ec199e7d8308e3763f", "lessThan": "c4d64534d4b1c47d2f1ce427497f971ad4735aae", "status": "affected", "versionType": "git" }, { "version": "ffbda8e9df10d1784d5427ec199e7d8308e3763f", "lessThan": "0a886489d274596ad1a80789d3a773503210a615", "status": "affected", "versionType": "git" }, { "version": "ffbda8e9df10d1784d5427ec199e7d8308e3763f", "lessThan": "4e39ecadf1d2a08187139619f1f314b64ba7d947", "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/vdpa/virtio_pci/vp_vdpa.c" ], "versions": [ { "version": "5.19", "status": "affected" }, { "version": "0", "lessThan": "5.19", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.119", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.63", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.11.10", "lessThanOrEqual": "6.11.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12", "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": "5.19", "versionEndExcluding": "6.1.119" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.19", "versionEndExcluding": "6.6.63" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.19", "versionEndExcluding": "6.11.10" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.19", "versionEndExcluding": "6.12" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/870d68fe17b5d9032049dcad98b5781a344a8657" }, { "url": "https://git.kernel.org/stable/c/c4d64534d4b1c47d2f1ce427497f971ad4735aae" }, { "url": "https://git.kernel.org/stable/c/0a886489d274596ad1a80789d3a773503210a615" }, { "url": "https://git.kernel.org/stable/c/4e39ecadf1d2a08187139619f1f314b64ba7d947" } ], "title": "vp_vdpa: fix id_table array not null terminated error", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "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": { "id": "CVE-2024-53110", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "version": "2.0.3", "timestamp": "2025-10-01T20:10:41.175338Z" } } } ], "problemTypes": [ { "descriptions": [ { "lang": "en", "type": "CWE", "description": "CWE-noinfo Not enough information" } ] } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2025-10-01T20:17:11.370Z" } }, { "title": "CVE Program Container", "references": [ { "url": "https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html" } ], "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2025-11-03T22:29:20.103Z" } } ] } }
