kernel: iommu/vt-d: Clear Present bit before tearing down PASID entry
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is being removed, the system may attempt to clear the entry before properly signaling to the hardware that the entry is no longer active...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-2026-89448
CVE-2026-89448 is a CRITICAL (CVSS 9.3) vulnerability in the Linux kernel's Intel VT-d IOMMU subsystem. The function detect_intel_iommu() fails to check for tboot when determining whether to request ACS (Access Control Services) . When tboot is enabled, tboot_force_iommu() forces the IOMMU on, bu...
PT-2026-90164
In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Force requesting ACS when tboot is enabled Currently the conditions of requesting ACS in detect intel iommu don't include tboot, leading to a possible misconfiguration with ACS disabled e.g. due to user opts while iom...
PT-2026-72875
In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Clear Present bit before tearing down scalable-mode context entry device pasid table teardown zeroes the 128-bit scalable-mode context entry with context clear entry while the Present bit is still set. This creates a...
CVE-2026-45945
In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Fix race condition during PASID entry replacement The Intel VT-d PASID table entry is 512 bits 64 bytes. When replacing an active PASID entry e.g., during domain replacement, the current implementation calculates a ne...
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...
