Title
hisi_acc_vfio_pci: Update migration data pointer correctly on saving/resume
Summary
In the Linux kernel, the following vulnerability has been resolved: hisi_acc_vfio_pci: Update migration data pointer correctly on saving/resume When the optional PRE_COPY support was added to speed up the device compatibility check, it failed to update the saving/resuming data pointers based on the fd offset. This results in migration data corruption and when the device gets started on the destination the following error is reported in some cases, [ 478.907684] arm-smmu-v3 arm-smmu-v3.2.auto: event 0x10 received: [ 478.913691] arm-smmu-v3 arm-smmu-v3.2.auto: 0x0000310200000010 [ 478.919603] arm-smmu-v3 arm-smmu-v3.2.auto: 0x000002088000007f [ 478.925515] arm-smmu-v3 arm-smmu-v3.2.auto: 0x0000000000000000 [ 478.931425] arm-smmu-v3 arm-smmu-v3.2.auto: 0x0000000000000000 [ 478.947552] hisi_zip 0000:31:00.0: qm_axi_rresp [error status=0x1] found [ 478.955930] hisi_zip 0000:31:00.0: qm_db_timeout [error status=0x400] found [ 478.955944] hisi_zip 0000:31:00.0: qm sq doorbell timeout in function 2

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\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"d9a871e4a143047d1d84a606772af319f11516f9\", \"lessThan\": \"45f80b2f230df10600e6fa1b83b28bf1c334185e\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"d9a871e4a143047d1d84a606772af319f11516f9\", \"lessThan\": \"6bda81e24a35a856f58e6a5786de579b07371603\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"d9a871e4a143047d1d84a606772af319f11516f9\", \"lessThan\": \"be12ad45e15b5ee0e2526a50266ba1d295d26a88\", \"versionType\": \"git\"}], \"programFiles\": [\"drivers/vfio/pci/hisilicon/hisi_acc_vfio_pci.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"6.2\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"6.2\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"6.6.14\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.7.2\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.7.*\"}, {\"status\": \"unaffected\", \"version\": \"6.8\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"drivers/vfio/pci/hisilicon/hisi_acc_vfio_pci.c\"], \"defaultStatus\": \"affected\"}], \"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\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nhisi_acc_vfio_pci: Update migration data pointer correctly on saving/resume\\n\\nWhen the optional PRE_COPY support was added to speed up the device\\ncompatibility check, it failed to update the saving/resuming data\\npointers based on the fd offset.
