About this tag
The iommufd tag on WindowsForum.com covers discussions about the Linux kernel's IOMMU userspace subsystem, which provides a userspace API for managing I/O page tables and I/O address spaces. Recent content includes a thread about a race condition vulnerability (CVE-2024-26785) in the iommufd subsystem that could lead to a local denial of service via a null-pointer or protection fault in the selftest ioctl paths. The patch for this issue is a targeted fix to close the locally exploitable vector. While the tag is Linux-specific, it may be of interest to Windows users running virtual machines or working with hardware pass-through scenarios where IOMMU management is relevant.
