there is no network-reachable path.\nAC:L - The defect is deterministic with no race — every reset or teardown of a virtio-pci device that negotiated VIRTIO_F_ADMIN_VQ indexes the wrong array, and a device supplying an arbitrary admin_queue_index controls the out-of-bounds offset exactly.\nPR:N - The out-of-bounds index originates from the device-supplied admin_queue_index MMIO field, and the faulty cleanup runs on the probe error paths (vp_find_one_vq_msix request_irq failure, vp_find_vqs_msix error_find, virtnet_probe free_vqs), so an untrusted virtio device triggers it during automatic driver binding with no guest/host credentials.\nUI:N - Device probe, hotplug, and reset happen automatically via the driver core; no victim action is needed.\nS:U - The out-of-bounds access and its consequences are confined to the kernel's own memory and security authority; no IOMMU, VM, or sandbox boundary is crossed.\nC:H - vp_dev->vqs[] is read past its kcalloc'd end by an unbounded, device-chosen 16-bit index, and the resulting pointer is dereferenced (info->vq, info->msix_vector) and handed to virtqueue_detach_unused_buf(), exposing adjacent and far-out-of-bounds kernel heap contents.\nI:H - The wild info pointer obtained from the out-of-bounds read is passed to list_del(&info->node) — which writes through two attacker-influenced pointers — and then to del_vq() and kfree(), yielding write and arbitrary-free primitives suitable for heap corruption and control-flow hijacking.\nA:H - The commit documents a reproducible kernel NULL pointer dereference oops in vp_reset()/vp_modern_avq_cleanup() on ordinary driver removal, and the corrupted list_del/kfree paths panic the kernel as well." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/virtio/virtio_pci_common.c", "drivers/virtio/virtio_pci_common.h", "drivers/virtio/virtio_pci_modern.c" ], "versions": [ { "version": "4c3b54af907e709609d3d8beca92d65e2f0cfd83", "lessThan": "018d3d4ad4be7fbc95d8a2367642a32d21df55c7", "status": "affected", "versionType": "git" }, { "version": "4c3b54af907e709609d3d8beca92d65e2f0cfd83", "lessThan": "97ee04feb682c906a1fa973ebe586fe91567d165", "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/virtio/virtio_pci_common.c", "drivers/virtio/virtio_pci_common.h", "drivers/virtio/virtio_pci_modern.c" ], "versions": [ { "version": "6.11", "status": "affected" }, { "version": "0", "lessThan": "6.11", "status": "unaffected", "versionType": "semver" }, { "version": "6.11.9", "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": "6.11", "versionEndExcluding": "6.11.9" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.11", "versionEndExcluding": "6.12" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/018d3d4ad4be7fbc95d8a2367642a32d21df55c7" }, { "url": "https://git.kernel.org/stable/c/97ee04feb682c906a1fa973ebe586fe91567d165" } ], "title": "virtio_pci: Fix admin vq cleanup by using correct info pointer", "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-2024-53092", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "version": "2.0.3", "timestamp": "2025-10-01T20:11:27.448573Z" } } } ], "problemTypes": [ { "descriptions": [ { "lang": "en", "type": "CWE", "cweId": "CWE-476", "description": "CWE-476 NULL Pointer Dereference" } ] } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2025-10-01T20:17:13.558Z" } } ] } }
