CVE-2020-29567

An issue was discovered in Xen 4.14.x. When moving IRQs between CPUs to distribute the load of IRQ handling, IRQ vectors are dynamically allocated and de-allocated on the relevant CPUs. De-allocation has to happen when certain constraints are met. If these conditions are not met when first checke...

CVE-2020-29567

CVE-2020-29567 affects Xen 4.14.x. When moving IRQs between CPUs, certain IRQ vector de-allocations may cause a CPU to self-interrupt, potentially causing a host DoS. A domain with a passed-through PCI device can trigger the issue; only x86 is vulnerable (Arm is not). Public details indicate reme...

infinite loop when cleaning up IRQ vectors

ISSUE DESCRIPTION When moving IRQs between CPUs to distribute the load of IRQ handling, IRQ vectors are dynamically allocated and de-allocated on the relevant CPUs. De-allocation has to happen when certain constraints are met. If these conditions are not met when first checked, the checking CPU m...

Rogue guests can cause DoS of Dom0 via high frequency events

ISSUE DESCRIPTION The handling of Xen events in the Linux kernel runs with interrupts disabled in a loop until no further event is pending. Whenever an event has been accepted by the kernel, another event can come in via the same event channel. This can result in the event handling loop running f...

CVE-2018-16882

A use-after-free issue was found in the way the Linux kernel's KVM hypervisor processed posted interrupts when nested=1 virtualization is enabled. In nestedgetvmcs12pages, in case of an error while processing posted interrupt address, it unmaps the 'pidescpage' without resetting 'pidesc' descript...
