Title
vfio/pci: Clean up DMABUFs before disabling function
Summary
In the Linux kernel, the following vulnerability has been resolved:
vfio/pci: Clean up DMABUFs before disabling function
On device shutdown, make vfio_pci_core_close_device() call
vfio_pci_dma_buf_cleanup() before the function is disabled via
vfio_pci_core_disable(). This ensures that all access via DMABUFs is
revoked before the function's BARs become inaccessible.
This fixes an issue where, if the function is disabled first, a tiny
window exists in which the function's MSE is cleared and yet BARs
could still be accessed via the DMABUF. The resources would also be
freed and up for grabs by a different driver.

{
"lang": "en",
"value": "AV:L - The vulnerable path is reached through local VFIO device file operations and ioctls, specifically exporting a VFIO PCI BAR DMA-BUF and then closing the VFIO device fd. It is not reachable by network packets or adjacent/physical-only input.\nAC:L - The attacker can set up the DMA-BUF/IOMMUFD mapping before triggering last-close, and the vulnerable cleanup ordering is deterministic. The P2P-capable VFIO/IOMMUFD environment is inherent to the affected feature rather than an uncontrollable exploitation condition.\nPR:L - The attacker needs local access to an assigned VFIO PCI device and IOMMUFD/VFIO file descriptors, but normal IOMMU-backed VFIO access does not require real root once the device node is delegated. This is privileged device access, but not necessarily administrator-level privilege.\nUI:N - No separate victim action is required after the attacker has the VFIO device fd. The attacker can export the DMA-BUF and trigger teardown by closing the fd.\nS:C - The bug can retain DMA-BUF access to PCI BAR MMIO after VFIO has disabled/released the function and potentially after resources are reassigned, crossing the VFIO/IOMMU device-ownership boundary. This is a DMA/IOMMU isolation bypass scenario.\nC:H - Stale peer-DMA access to MMIO BAR ranges can expose device registers or newly reclaimed MMIO resources outside the attacker\u0027s assigned VFIO device. In a severe reasonable deployment such as GPU, NIC, NVMe, or accelerator passthrough, this can disclose sensitive host, device, or guest data.\nI:H - The retained DMA-BUF mapping can allow unauthorized writes to MMIO registers or resources that should have been revoked, potentially programming device state or DMA behavior outside the attacker\u0027s ownership. That supports high integrity impact across the device isolation boundary.\nA:H - Accessing BAR MMIO after memory space is disabled or while resources are being reclaimed can crash or wedge devices and can trigger serious platform errors on sensitive systems. Repeated local triggering can therefore cause high availability impact."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
