CVE-2026-45862

A flaw was found in the Linux kernel's IOMMU Input/Output Memory Management Unit virtualized directed I/O VT-d component. When a freshly allocated PASID Process Address Space ID table is written to a directory entry, the CPU cache flush for this table occurs too late. This creates a time window...

CVE-2026-45944

A flaw was found in the Linux kernel's IOMMU Input/Output Memory Management Unit VT-d Virtualization Technology for Directed I/O component. When a context entry is being torn down, the 'Present' bit might not be cleared before other parts of the entry are zeroed. This can lead to the hardware...

UBUNTU-CVE-2026-45944

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...
