CVE-2026-43161

A flaw was found in the Linux kernel's Intel IOMMU Input/Output Memory Management Unit virtual technology for directed I/O VT-d subsystem. When a PCIe Peripheral Component Interconnect Express endpoint device, especially when passed through to userspace applications like QEMU or DPDK, unexpectedl...

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

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

In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Flush dev-IOTLB only when PCIe device is accessible in scalable mode Commit 4fc82cd907ac "iommu/vt-d: Don't issue ATS Invalidation request when device is disconnected" relies on pcidevisdisconnected to skip ATS...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the fact that the iommu vt-d does not check whether PCIe devices are accessible in extended mode,...
