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...
