Linux · Linux Kernel · CVE-2014-3601
**Name of the Vulnerable Software and Affected Versions**
Linux kernel versions prior to 3.16.1
**Description**
The issue arises from a miscalculation in the number of pages during the handling of a mapping failure in the `kvm iommu map pages` function. This allows guest OS users to cause a denial of service, either through host OS memory corruption by triggering a large `gfn` value or through host OS memory consumption by triggering a small `gfn` value, leading to permanently pinned pages.
**Recommendations**
For Linux kernel versions prior to 3.16.1, update to version 3.16.1 or later to resolve the issue.
