Last modified
CVE-2015-4103 is a vulnerability of currently unknown severity. Xen 3.3.x through 4.5.x does not properly restrict write access to the host MSI message data field, which allows local x86 HVM guest administrators to cause a denial of service (host interrupt handling confusion) via vectors related to qemu and accessing spanning multiple fields.. EPSS estimates a 0.45% chance of exploitation in the next 30 days.
