About this tag
The cve 2026 68329 tag on WindowsForum.com covers discussions about CVE-2026-68329, a Linux kernel vulnerability in the AMD IOMMU driver. This flaw is a use-after-free race condition that could allow code execution after an IOMMU synchronization request, even though earlier invalidation commands were still running in hardware. The issue affects Linux systems using AMD-Vi/IOMMU translation, particularly virtualization hosts, PCI passthrough workstations, and systems with frequent DMA mapping changes. It does not affect ordinary Windows installations. The tag includes details on fixed versions, such as Linux 6.6.148, 6.12.101, 6.18.42, 7.1.6, and 7.2-rc5, and references the NVD record and kernel.org sources.
