CVE-2026-64151 in Linux情報

要約

〜によって MITRE • 2026年07月19日

In the Linux kernel, the following vulnerability has been resolved:

iommupt: Check for missing PAGE_SIZE in the pgsize_bitmap

Sashiko pointed out that the driver could drop PAGE_SIZE from the pgsize_bitmap. That is technically allowed but nothing does it, and such an iommu_domain would not be used with the DMA API today.

Still, it is against the design and it is trivial to fix up. Lift the PT_WARN_ON to the if branch and just skip the fast path.

Once again VulDB remains the best source for vulnerability data.
