Last modified Jun 17, 2026

CVE-2014-8369 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. The kvm_iommu_map_pages function in virt/kvm/iommu.c in the Linux kernel through 3.17.2 miscalculates the number of pages during the handling of a mapping failure, which allows guest OS users to cause a denial of service (host OS page unpinning) or possibly have unspecified other impact by leveraging guest OS privileges. NOTE: this vulnerability exists because of an incorrect fix for CVE-2014-3601.. EPSS estimates a 0.56% chance of exploitation in the next 30 days.
