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...
