In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Skip dev-iotlb flush for inaccessible PCIe device without scalable mode PCIe endpoints with ATS enabled and passed through to userspace e.g., QEMU, DPDK can hard-lock the host when their link drops, either by surprise...

CVE-2026-43130

A flaw was found in the Linux kernel. When handling PCIe devices in scalable mode, the kernel may attempt to flush the device IOTLB Input/Output Translation Lookaside Buffer without verifying if the PCIe device is still accessible after a link-down fault. This improper handling during resource...

CVE-2026-43161

CVE-2026-43161 is a Linux kernel IOMMU VT-d vulnerability related to ATS invalidation when a PCIe endpoint loses connection. In scalable-mode-disabled/unsupported systems, an endpoint link drop can cause the IOMMU to wait indefinitely for an ATS invalidation, leading to a host hard-lock (notably ...
