CVE-2026-45944 iommu/vt-d: Clear Present bit before tearing down context entry

In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Clear Present bit before tearing down context entry When tearing down a context entry, the current implementation zeros the entire 128-bit entry using multiple 64-bit writes. This creates a window where the hardware c...

CVE-2026-45944

CVE-2026-45944 affects the Linux kernel IOMMU VT-d. During context-entry teardown, the implementation zeros a 128‑bit entry in two 64‑bit writes, risking a torn entry where the Present bit remains set while other fields are zeroed, potentially causing unpredictable behavior or spurious faults. Th...

CVE-2026-45894

The CVE-2026-45894 issue affects the Linux kernel IOMMU VT-d Scalable Mode PASID handling. When a PASID table entry is torn down, the current code zeros the full 64-byte structure while P=1, risking a torn read if hardware fetches the 64 bytes concurrently. Mitigation directs an ownership handsha...
