SUSE CVE-2026-45862
In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Flush cache for PASID table before using it When writing the address of a freshly allocated zero-initialized PASID table to a PASID directory entry, do that after the CPU cache flush for this PASID table, not before i...
SUSE CVE-2026-45894
In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Clear Present bit before tearing down PASID entry The Intel VT-d Scalable Mode PASID table entry consists of 512 bits 64 bytes. When tearing down an entry, the current implementation zeros the entire 64-byte structure...
CVE-2026-45894
A flaw was found in the Linux kernel's Intel VT-d Virtualization Technology for Directed I/O Scalable Mode. When a Process Address Space ID PASID table entry is being removed, the system may attempt to clear the entry before properly signaling to the hardware that the entry is no longer active...

CVE-2026-45862
The CVE-2026-45862 issue concerns the Linux kernel’s IOMMU VT-d PASID handling. A flaw in the cache flush order when writing a freshly allocated zero-initialized PASID table to a PASID directory entry creates a time window during which non-coherent IOMMU hardware could access RAM contents that ar...
PT-2026-43812
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A race condition exists in the Intel VT-d PASID table entry replacement process. The PASID table entry is 512 bits, and the implementation copies a new entry to the table using a single...
