CVE-2026-43161 iommu/vt-d: Skip dev-iotlb flush for inaccessible PCIe device without scalable mode

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

The CVE-2026-43130 issue affects the Linux kernel iommu/vt-d path, where flushing the dev-IOTLB can occur during resource release in scalable PCIe mode. The root cause is a path that attempted ATS invalidation without adequately verifying whether the PCIe device is still accessible after a link-d...

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...

Rowhammer Attack Against NVIDIA Chips

A new rowhammer attack gives complete control of NVIDIA CPUs. On Thursday, two research teams, working independently of each other, demonstrated attacks against two cards from Nvidia’s Ampere generation that take GPU rowhammering into new--­and potentially much more consequential--­territory: GDD...

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,...
