CVE-2013-1952 is a vulnerability of currently unknown severity. Xen 4.x, when using Intel VT-d for a bus mastering capable PCI device, does not properly check the source when accessing a bridge device's interrupt remapping table entries for MSI interrupts, which allows local guest domains to cause a denial of service (interrupt injection) via unspecified vectors.. EPSS estimates a 0.42% chance of exploitation in the next 30 days.
