CVE-2015-8554
Last modified
CVE-2015-8554 is a vulnerability of currently unknown severity. Buffer overflow in hw/pt-msi.c in Xen 4.6.x and earlier, when using the qemu-xen-traditional (aka qemu-dm) device model, allows local x86 HVM guest administrators to gain privileges by leveraging a system with access to a passed-through MSI-X capable physical PCI device and MSI-X table entries, related to a "write path.". EPSS estimates a 0.40% chance of exploitation in the next 30 days.
