kernel: kvm: pit timer with no irqchip crashes the system

The createpittimer function in arch/x86/kvm/i8254.c in KVM 83, and possibly other versions, does not properly handle when Programmable Interval Timer PIT interrupt requests IRQs when a virtual interrupt controller irqchip is not available, which allows local users to cause a denial of service NUL...

VT-d (PCI passthrough) MSI trap injection

ISSUE DESCRIPTION Intel VT-d chipsets without interrupt remapping do not prevent a guest which owns a PCI device from using DMA to generate MSI interrupts by writing to the interrupt injection registers. This can be exploited to inject traps and gain control of the host. VULNERABLE SYSTEMS You ar...
