interrupt remap entries shared and old ones not cleared on AMD IOMMUs

ISSUE DESCRIPTION To avoid an erratum in early hardware, the Xen AMD IOMMU code by default chooses to use a single interrupt remapping table for the whole system. This sharing implies that any guest with a passed through PCI device that is bus mastering capable can inject interrupts into other...

Linux pciback DoS via not rate limited log messages.

ISSUE DESCRIPTION Xen's PCI backend drivers in Linux allow a guest with assigned PCI devices to cause a DoS through a flood of kernel messages, potentially affecting other domains in the system. IMPACT A malicious guest can mount a DoS affecting the entire system. VULNERABLE SYSTEMS All systems...

CVE-2012-5634

Xen 4.2.x, 4.1.x, and 4.0, when using Intel VT-d for PCI passthrough, does not properly configure VT-d when supporting a device that is behind a legacy PCI Bridge, which allows local guests to cause a denial of service to other guests by injecting an interrupt...

VT-d interrupt remapping source validation flaw

ISSUE DESCRIPTION When passing a device which is behind a legacy PCI Bridge through to a guest Xen incorrectly configures the VT-d hardware. This could allow incorrect interrupts to be injected to other guests which also have passthrough devices. In a typical Xen system many devices are owned by...
